General chats exist within courses, and you can only access general chats from within the course in which they are created.
All users in the course have access to the general chat. You can create multiple chats for the same course, such as “Midterm Review” and “Final Review.” It is a good idea to enter a description to help other users identify the chat, since they might have access to other chats with similar names. Users from other course offerings will not be able to access this chat.
