Microsoft Teams video conference?

I have a question about video conferencing at Microsoft Teams. As a teacher, can you see after a video conference whether a student has secretly taken a screenshot with his mobile phone / laptop during the conference?

No I do not think so. A screenshot is taken from the device itself. My father is a teacher, he has never said anything about it. And never before, even though I've often taken screenshots.

So I'm relatively sure that they can't. And most teachers don't care either.

And even if he could: You can say that it was unintentional and that you have already deleted it.

Nevertheless, I would advise against screenzhott people and then spreading it, because that would no longer be legal.
