My school recently switched over to using teams because of the corona virus pandemic, so anyone in my school can privately chat me. I do not like the feature. 1) you should be able to send a request, asking if I can privately chat with someone. If they refuse, you cannot chat with them. If they accept, you can chat with them. 2) I believe that you should be able to block someone. I have recently been able to mute someone, but I still receive their messages! So please, Microsoft, make a feature that allows people to block people.
