Nah - you'll have to try connect them on simplex.
It'll take a while but the people who you care about will make the shift.

Funny story, they tried simplex and hated it 😂
It's improved a lot since a few years ago.
I've got a few contacts that say I'm the only 1 they have on simplex. They say this to me on Simplex as they bitch about having to use it to contact me. 🤣
Escaping Telegram to move to Signal was one of dumbest moves I've seen.
I'm hopeful of white noise but I'm bullish on Simplex.
We were using simplex 6 days ago, but switched to signal due to group preferences.
