Teams is widely employed as an "educational/teaching software/channel". Nevertheless, there's no way to control "active" presence of participants (sometimes they switch off their camera and leave conciously the call pretending to pay attention). It would be useful if an image is randomly shown (every x minutes) and participant should be forced to solve it -otherwise an alert is registered-.
