In Telegram ,for example we have a user with first name= Jim and last name=Smith. He may have a public username or not.(no problem) and has a unique id. Already you know this person is known for his friend with different names(niknames) in telegram contact list and in chats or groups, someone may see "Jimmm", the other see him "My best friend" the other see him "J S" and so on.
The question is how to send a message to a group and mention him (Via BOT) that he and his friends are in that group ,and mention him so that each friend see this message in his/her own way.(No 1. friend see him "Jimmm", the next see him "My best friend" and the third see him "J S"). The Problem is mentioning of him in a message ,in a way that everyone see him in themselves manner. thanks in advance.
