There is no way to delete a chat. The history grows without bound and users cannot remove conversations they would rather not keep.

What problem are you trying to solve?

Allow deleting a chat from the history list and from within the chat.

Proposed solution

• Delete available from both places
• Confirmation before deletion (see the destructive-actions issue)
• Associated sandbox state and attachments are cleaned up, not orphaned
• Deletion behaviour documented — soft vs hard, and what an operator can recover
