Is there a way to know the current number of people in the conference using Android SDK?

Hello,

I am developing an Android project and I created an activity and implemented JitsiMeetActivityInterface and JitsiMeetViewListener from it. Now I want to know the current number of participants in a meeting because I will end the conference if only one person is left.

If there is a way I would like to know. (A method or an attribute, etc)
