{
    /// <summary>
    /// The Interactor associated with the interaction event.
    /// </summary>
    public new IXRHoverInteractor interactorObject
    {
        get => (IXRHoverInteractor)base.interactorObject;
        set => base.interactorObject = value;
    }
/// <summary>
/// The Interactable associated with the interaction event.
/// </summary>
public new IXRHoverInteractable interactableObject
{
    get => (IXRHoverInteractable)base.interactableObject;
    set => base.interactableObject = value;

### Handling XR Interaction Manager Registration Events

Source: https://docs.unity3d.com/Packages/com.unity.xr.interaction.toolkit%403.5/api/UnityEngine.XR.Interaction.Toolkit.InteractableSnapVolumeRegisteredEventArgs.html

This example demonstrates how to subscribe to and handle registration and unregistration events for XR interaction components like Interaction Groups, Interactors, Interactables, and Snap Volumes. It shows how to create callbacks for each event and log messages when components are registered or unregistered. Ensure an XRInteractionManager is present in the scene.

```csharp

        m_InteractionManager = FindAnyObjectByType<XRInteractionManager>();

    // Note, the code below is creating the XRInteractionGroup, NearFarInteractor, XRGrabInteractable, and XRInteractableSnapVolume before subscribing
    // to the interaction manager register/unregister events. Therefore, the initial register callback will not be logged.
    // To demonstrate these callbacks, enable/disable each example game object in the hierarchy to receive the register/unregister callbacks.

    // XRInteractionGroup automatically registers with the interaction manager on Awake
    var interactionGroupGO = new GameObject("Example Interaction Group");
    m_ExampleInteractionGroup = interactionGroupGO.AddComponent<XRInteractionGroup>();
