I have been able to re-share my documents to new meeting participants, using the top-right 'share' icon. This does the job but as mentioned by others, it has to be done for each individual file and that's a chore. It also breaks up the flow of conversation, looses context, and can't be filtered out. In my case the new participant was added via Outlook Calendar (Desktop App), so they neither have access to the chat history nor files, meeting notes, etc. I can see that security might be a concern so how about this? Allow the meeting owner (or their delegate) to retrospectively provide access to chat history, make access requests to document owners on behalf of new participants, and similar mechanisms for other features that are accessible from a meeting.
