getWindowDidHideStream method
You can listen for when the Intercom window is hidden.
This stream emits when the Intercom window (messenger, help center, etc.) is closed. This allows developers to perform certain actions in their app when the Intercom window is closed. Only available on iOS.

@override
Stream<dynamic> getWindowDidHideStream() {
return _windowDidHideChannel.receiveBroadcastStream();
}
