Clean up chats and bubbles that are older than a defined period.

We'd like a feature that allows users to delete older posts in a chat, for example, posts older than a year. Currently, there aren't many cleanup options. In chats, the only option is to delete all messages. Bubbles offer a similar feature, but with the added limitation that you have to be the "owner" of the bubble to do so.

Perhaps there's a smart way to assist users with cleanup, instead of simply presenting them with an "all or nothing" choice?

Of course, GDPR-compliant cleanup is also crucial. We don't want deleted posts lingering on some server indefinitely.
