Normally telegram is a home for scammers,  not only telegram though even x and some other big platform. They usually message on X (twitter) . But I don't bother striking any conversation with them I just ignore it because have already know that they are not here with good intentions. That's why if a friend contact you like the screenshot op posted the best thing to do is to call that same  friend and make sure he was truly the one that contacted you via the platform.
