### Install Watson Assistant Web Chat using Script Tag

Source: https://web-chat.global.assistant.watson.cloud.ibm.com/docs.html/index_to=api-overview

This method installs the Watson Assistant web chat using a script tag, making it framework-agnostic. It dynamically loads the chat script from a CDN and requires integrationID, region, and serviceInstanceID for initialization. The onLoad callback is used to render the widget.

```html
<script>
  window.watsonAssistantChatOptions = {
    // A UUID like '1d7e34d5-3952-4b86-90eb-7c7232b9b540' included in the embed code provided in watsonx Assistant.
    integrationID: 'YOUR_INTEGRATION_ID',
    // Your assistants region e.g. 'us-south', 'us-east', 'jp-tok' 'au-syd', 'eu-gb', 'eu-de', etc.
    region: 'YOUR_REGION',
    // A UUID like '6435434b-b3e1-4f70-8eff-7149d43d938b' included in the embed code provided in watsonx Assistant.
    serviceInstanceID: 'YOUR_SERVICE_INSTANCE_ID',
    // The callback function that is called after the widget instance has been created.
    onLoad: async (instance) => {
      await instance.render();
    }
  };
  setTimeout(function(){const t=document.createElement('script');t.src='https://web-chat.global.assistant.watson.appdomain.cloud/versions/' + (window.watsonAssistantChatOptions.clientVersion || 'latest') + '/WatsonAssistantChatEntry.js';document.head.appendChild(t);});
</script>

Source: https://web-chat.global.assistant.watson.cloud.ibm.com/docs.html/index_to=api-events

An example handler function that processes messages for session history, censoring specific words and hiding entire messages if a certain phrase is detected.

```APIDOC
## agent:pre:startSessionHistory Handler Example

### Description
This handler processes messages between the user and an agent to modify them before they are added to the session history. It replaces occurrences of the word "secret" (case insensitive) with "******" and hides the entire message if it contains the phrase "hide this message".

### Method
Event Handler (for `agent:pre:startSessionHistory`)

### Endpoint
N/A (Event-driven)

### Parameters
#### Path Parameters
N/A

#### Query Parameters
N/A

#### Request Body
**event** (`Object`) - The event object containing message data.
- **message** (`Object`) - Contains input from the user or output from the agent.
  - **output** (`Object`) - Contains the agent's response.
    - **generic** (`Array`) - An array of message objects, typically containing text.
  - **input** (`Object`) - Contains the user's input.
    - **text** (`String`) - The text content of the user's message.

**instance** (`Object`) - The current instance of the web chat (used for event registration).

### Request Example
```javascript
// Assuming 'instance' is an initialized Web Chat instance

async function agentPreSessionHistoryHandler(event) {
  let hideWholeMessage = false;
  if (event.message.output) {
    // This is a message from an agent.
    event.message.output.generic.forEach(item => {
      // This code is only handling text messages. If the service desk can produce other types of message responses,
      // (such as image responses), you need to add additional code for each of those possible types.
      if (item.text) {
        item.text = item.text.replace(/secret/gi, '******');
        if (item.text.toLowerCase().includes('hide this message')) {
          hideWholeMessage = true;
        }
      }
    });
  } else if (event.message.input) {
    // This is a message from a user.
    event.message.input.text = event.message.input.text.replace(/secret/gi, '******');
    if (event.message.input.text.toLowerCase().includes('hide this message')) {
      hideWholeMessage = true;
    }
  }

  if (hideWholeMessage) {
    event.message = null; // Hides the entire message from history
  }
}

instance.on({ type: 'agent:pre:startSessionHistory', handler: agentPreSessionHistoryHandler });
```

### Response
#### Success Response (Event Handled)
- The `event.message` object is modified in place. If `hideWholeMessage` is true, `event.message` is set to `null`.

#### Response Example
(See Request Example for logic. The actual session history modification depends on the web chat's internal handling after this event resolves.)

### instance.showLauncherGreetingMessage()

Source: https://web-chat.global.assistant.watson.cloud.ibm.com/docs.html/index_to=api-instance-methods

Controls the timing of the greeting message appearance. Allows setting specific times for desktop and mobile launchers.

```APIDOC
## instance.showLauncherGreetingMessage()

### Description
This method controls the timing of when the greeting message appears. The default behavior is that the greeting message appears after 15 seconds. If the greeting message is already visible, then it ignores any new set times. If the greeting message is visible to the user when the page changes or reloads, the greeting message remains visible when reloading. The updated timing does not save in the session storage; if the user changes pages or reloads the page before the greeting message appears, the updated timing needs to be set again. This can not be used to change the greeting text of the launcher. If you want to change the text use instance.updateLauncherGreetingMessage().

### Method

#### Path Parameters
None

#### Query Parameters
None

#### Request Body
None

#### Method Parameters
- **time** (Number) - Optional - The number of milliseconds until the launcher should display the greeting message. For example, passing `4000` would imply that the greeting message should be shown four seconds from now. If no time is passed, then the greeting message appears immediately.
- **launcherType** (String) - Optional - There are two different launchers that appear depending on the end user's device type: a desktop and a mobile launcher. `launcherType` can be used to specify which launcher the new timing should be set for; valid options are either `mobile` or `desktop`. If no `launcherType` is passed, then the timing sets for both.

### Request Example
```javascript
// To show the desktop launcher in 4s (the mobile launcher shows at the original 15s interval).
instance.showLauncherGreetingMessage(4000, 'desktop');

// To show the mobile launcher in 6s (the desktop launcher would still plan to show in 4s).

### Screen Sharing Integration

Source: https://web-chat.global.assistant.watson.cloud.ibm.com/docs.html/index_to=service-desks-custom-sd

Enables integration with service desk provided screen sharing or co-browsing capabilities. It allows requesting user permission to start screen sharing and stopping it.

```APIDOC
## Screen Sharing

### Description
Integrate screen sharing or co-browsing capabilities provided by your service desk. The web chat facilitates requesting user approval for screen sharing and allows the user to stop the session. The web chat itself does not provide screen sharing functionality; it acts as an intermediary for permission requests.

### Functions

#### `callback.screenShareRequest()`

*   **Description**: Initiates a screen sharing request to the user. A modal will appear asking the user for approval. This function returns a Promise that resolves with the user's response (approve/deny).
*   **Returns**: `Promise<boolean>` - Resolves to true if the user approves, false otherwise.

#### `callback.screenShareStop()`

*   **Description**: Stops the screen sharing session. This can be called at any time, including while waiting for user approval, to implement timeouts or user-initiated cancellations.

### User-Initiated Stop

*   **Description**: If the user stops screen sharing, the web chat will call the `screenShareStop` function on your integration.
