Confidentiality of meeting chats for participants that are forwarded the invite once off/ called in
Often, a participant is called into a meeting/ forwarded a meeting once off to present/ stand in. Unless the actively leave the meeting or someone removes them, they will continue to see chats related to that meeting. Is it not possible to automatically expire a participant with a once off invite/ that was called in? Else can the chats not be visible to them if forwarded the meeting/ called in? This is to manage confidentiality risk.
