How to know in real time who is inside a meeting ? Prosody presence...?

I would like to know if there is a mechanism that indicates the people present in a meeting in real time.
An attendance control system.

We have added a login mechanism (username and password) to Jitsi meet and I would like to use the username (email) as a discriminating factor to recognize people in meetings, or in the case of a sip call via the telephone number.

On another company platform that uses the same users (email or telephone number to trace a user), we would like to have the presence of jitsi so as to know in real time whether the user is engaged or not in a meeting.

Can you help me?

You can use this to report such information to another system: prosody-plugins/event_sync at main · jitsi-contrib/prosody-plugins · GitHub
