Venomancer I don't think that Session has this feature, I checked but I dound nothing.
Yes, the only problem is that most of my friends don't care about privacy.
Obviously, I prefer Signal but the only thing that I don't like with Session is that conversations can't be saved if I change of device
Yes, I heard that Telegram encryption is not strong at all, but unfortunately this is the only app that some of my friends use.
I try step by step to convince them to change to Session or at least Signal.
I've heard about Status.im too which seems interesting but Session looks better
