According to machine translation, your question is:
Can Microsoft Teams detect cheating done by users outside of Teams windows?
If there is any misunderstanding, please feel free to point out.
If the scenario is like:
A user is taking an interview in Teams meeting and he is showing his camera and sharing a window (for example showing a PPT to the interviewer), while he is cheating by checking some contents in another window which is not shared in Teams.
In this case, the interviewer would not be able to know the user is cheating.
