Porque me botan de la reunión?

Continuing the discussion from Porque me botan de la reunión? Why am I kicked out of the meeting?:

I have created it through Jitsi and it has generated the link (https: //meet.jit.si/DSI-SEGUNDO …) which I share with my students, but I see that there is someone in the room (one of the students) who is throwing away the teacher and changing the names and we don’t know who he is. My question was if this action could be blocked so that this person does not continue throwing or blocking any member? How to know who is in the meeting? is there any way
