function showModal() {
  console.log("open");
  modal.open();
  // testEventEmitter.emit("connecting", { connector: "auth" })
  // testEventEmitter.emit("errored", { error: new Error("something went wrong") })
  // testEventEmitter.emit("connected", { connector: "wallet-connect-v1" })
  // testEventEmitter.emit("disconnected", { connector: "wallet-connect-v1" })
}

(async function init() {
  try {
    testEventEmitter = new Auth.SafeEventEmitter();
    modal = new Ui({
      adapterListener: testEventEmitter,
      theme: "dark",
      // version: "1",
    });
    await modal.initSdk();
    console.log("modal init");

    modal.addSocialLogins(
      "auth",
      {
        google: { name: "google" },
        facebook: { name: "facebook" },
        twitter: { name: "twitter" },

        twitch: { name: "twitch" },
        github: { name: "github" },
      },
      ["facebook"]
    );

    modal.initExternalWalletContainer();
    modal.addWalletLogins(
      {
        "wallet-connect-v2": {
          label: "wallet-connect-v2",
        },
      },
      { showExternalWalletsOnly: false }
    );

    testEventEmitter.emit("connector_data_updated", {
      connectorName: "wallet-connect-v1",
      data: { uri: "alslkslkalls" },
