Echobot, how to make it leave the call

[jamil-z]

Describe the issue

hello! I would like some help with this, because when I have a group call, the bot joins correctly. After we all leave the call, echobot remains in the call. How could I make it leave when it detects that there are no participants left in the call?"

Code Snippet Insert the code snippet if any.

Expected behavior when detecting that there is no one left in the call, the bot should also leave, so that the group chat call ends
