How to register in a telegram bot through a phone number, so that later you can log in to the bot for your function?

Answer 1

The mechanisms can be different...
I associate an ID that is passed with each message and a phone number that the user can pass to the bot by clicking "Submit your contact".
"contact": {
"phone_number": "Number",
"first_name": "nickname",
"user_id": id"
}
