How can I disable participants from turning off the mics of others and sharing their own desktops?

• Create meeting
• From Microsoft  Teams, go to Calendar  , select a meeting, and then Meeting options.
• If you have not scheduled a meeting, you may do this by selecting  Show participants    in the meeting controls. Then, above the list of participants, choose Manage permissions .
• You may choose to have students wait for you and you can choose whether to admit or deny them.
• You may wish not to allow students present.  This is important so that students won’t share their  screens etc.  In this case select “Only me”
