Hi
My name is Daniel. I am an Independent Advisor.
It's hard to stop them from doing the things you mentioned above.
In order to reduce the possibility for students from cheating, Microsoft Teams has built-in similarity checks on student assignments named Turnitin. This feature streamlines the grading process while reinforcing to students the importance of creating authentic work.
Please refer to this article:

A Turnitin license is required in order to use the integration with Assignments in Teams. If you have a Turnitin subscription, IT Admins can sign up to enable the integration here. https://www.turnitin.com/products/feedback-stud...
