Empathy Sessions - don't show historical chat

We would like a new setting in empathy sessions to prevent the historical chat from being displayed to users who join. This is because we conduct empathy sessions with customers of ours who are competitors so we don't want them in the session at the same time, but we also don't want to have dozens of empathy sessions in Aha! on the same topic as the disperses the feedback and makes it hard to consolidate.

It seems like a setting to hide the chat history when a new user joins would allow us to conduct multiple sessions within the same session and maintain customer privacy. It would also be nice to have a checkbox option next to users to send them invites so we don't accidentally send invites to individuals from multiple companies for one session.
