share chat history when adding third participant to a chat
When you add a third participant to a chat (i.e. convert it from a private chat to a group chat) you should be able to share the history of the chat, just like when you add a 4th, 5th, 6th, etc. to a group chat. Allow users to share, not share, share last X days, or select specific messages that should be shared.

I've been getting a lot of requests for this. When adding a 3rd participant, we would like the option to share the history from X hours/days so they're not able to see everything and keep the full history private.
