Add time limit to keep messages.

Why do you want this feature?

To forget old messages

Additional information

Like signal or whatsapp it would be great to be able to set retaining time for messages. Preferably per conversation setting. So that I could set that messages are automatically removed after 1 week, 1 month or similar.

A global retention period setting and a per-conversation setting would be great.
