Hard mute and unmute
Provide an option for organiser to mute the participants (already there) and participants could not unmute themself, if this is applied, organiser can choose whether he/she is willing while scheduling the meeting (meeting options).
UNMUTE: If organiser would like to unmute a participant, if he/she calls a participant's name, that participant should raise hand and the organiser can unmute. Unless the participant raise his/her hand the organiser couldn't unmute the participant due to the privacy problem. Because the students are cheating the teachers as they are in the meeting. Thank you.
This is also needed for children with movement challenges who can't physically unmute themselves as well.

Absolutely necessary for classroom.... so much easier to teach and mediate if mtg leader has control over muting attendees. This would be also true for video... if mTG leader sees something is on video that shouldn't the leader can turn it off
