Add more user camera controls.
Enable the teacher to flip the camera view on different axis. I'm a math teacher. During meetings, the students' view shows my writing backwards.
My experience is that Teams assume that you use a front-facing camera and as such shows it to you in a reversed/flipped view (and there are good reasons for that) but the rest of the audience still see the correct view.
If you are using a rear facing or independent camera, this might be a problem.

Also increase camera controls like in skype. Allow for focus, pan, tilt, etc.
