Conversations involving multiple participants, allowing collaboration and information sharing in Teams
Honestly I can't believe Microsoft has missed this feature. Obviously people will want to record their meetings and the results of them. In our meetings, people use the chat to share links, files, ask questions and we need to capture all of these components. When the meeting is an "info session" we have people not contained within a "channel" and therefore the features associated with channel meetings are not helpful. Being able to copy / paste (or better yet, export the chat content) should have been identified early on by Microsoft.
