we pushed it behind teams, but we'll do it soon. 2 things we want to work on shortly:
(1) switching to short-term exploding message mode (what you would expect from OTR), so your messages can be read and then disappear. And devices don't cache them. This has inconveniences, especially for team chat, but it's what you might want in certain sensitive situations or certain DM's.
(2) a message auto-deletion policy for the team. This is different, and it's been requested by some testers.
