"Knock Knock" on User enters Lobby

Greetings everyone!

We enabled the lobby feature and now we would like to play a sound file on the moderator jitsi window.

Person A is waiting in a Room X for Person B. B now wants to join X. A is currently working in another window or just not paying attention to the jitsi window, thus he wont allow B.

Is it possible to play a sound file on the window of A to notify him “Hey someone wants to enter the room”?

We have installed jitsi on our own Server.

Thanks, in advance :slight_smile:
