[Improvement] Ask confirmation before share contact info

[Ecron]

Hi there! Something that happened to me a couple of times is that, when I talk to people who I don't have their numbers through Telegram, I accidentally tap over Share contact info button, sharing my number with extrangers. So it would be a good thing that Telegram ask for your confirmation before doing it.

What do you think? :smile:
