twitchChatError.md

The app has a button with the following function as a click handler

const doChatStuff = () => {
  const clientId = '123';
  const nick = 'twitch_name';
  const url = `https://id.twitch.tv/oauth2/authorize?client_id=${clientId}&redirect_uri=slobs-oauth://jingle_punks&response_type=token&scope=chat:edit&scope=chat:read`;
  try {
    window.streamlabsOBS.v1.Authorization.showAuthorizationWindow(
      url, { width: 600, height: 800 },
      event => {
        if (event.type === 'auth_redirect') {
          const token = parseTokenFromUrl(event.url);
          window.Streamlabs.twitch.initTwitchChat({ nick, token })
          window.Streamlabs.sendChatMessage('Hello World!')
        }
      }
    );
  } catch (e) {
    console.error(`Twitch auth FAILED:`, e)
  }
}

after clicking this button, the following error appears in the console:

then another button is clicked with the following onClick handler:

() => window.Streamlabs.sendChatMessage('Hello World!')

clicking that button yields this error:
