I use apps with both of these capabilities.

They were switching from a discord. I don't think they found any option functional enough. Do you mean coracle private groups? What's the other private group messaging thing, I forget (?). Neither are really ready enough or have adequate features for this scenario, maybe. They wanted off discord with little hassle and the same / similar functionality. ¯⁠\⁠_⁠(⁠ツ⁠)⁠_⁠/⁠¯ What would you have suggested? One of them had a look around various options but didn't find a good fit.
