In general, it is a good idea for each course to have its own Microsoft Team. This provides the following capabilities:
A dedicated chat channel that can serve for both ongoing text chats as well as a location to hold video meetings.
A Sharepoint file storage location that can be used for files that need to be shared with TAs or students. (Note: Primary copies of documentation, including manuals and other course content, should not be stored in the course-specific Team, but rather in the ECE Lab Instructors Sharepoint area.)
