Hello @OscarSuarezV - thanks to @johnod120 for providing you with the announcement of the Microsoft Teams Assignment LTI now being available in Canvas. I read over the Canvas Admin Deployment Guide and my conclusion is that while an institution can install Teams to a Canvas subaccount to make the tool available to a large number of courses, the tool can also be installed to a single course. As a first step I suggest checking in with your Canvas Admin or perhaps your IT Dept. to see what process they have for testing, evaluating, and installing new LTI tools.
Good luck!
Best, Jeff
ps. I just noted that Microsoft is offering a course for educators to help us become familiar with the Teams LTI Canvas integration.
