Telegram Username and Mobile Number Scraper (REPOST)

I would like you to make a software from which I can extract the usernames and mobile numbers from any Telegram Groups AND channels. The software must have nice interface and be easy and simple to use. I must also have a bulk messaging module on it, or a way for adding all the extracted telegram usernames to any new group or channel i create also because there is no use for telegram usernames until and unless i can send them my offers. So Extracting usernames as well as adding this usernames to a new group/channel and sending them messages must be included. But the MOST IMPORTANT feature i need on this program is the ability to scrape PHONE NUMBERS from any telegram group/channel and it must be in a '' ORGANIZED '' way/format specifying the username of the owner of the phone number scraped etc... If you can't do anything else from the project, except this then you will have made me very happy already. THE PROGRAM MUST BE ABLE TO EXTRACT USERNAMES/MOBILE NUMBERS FROM TELEGRAM CHANNELS THAT I'M NOT THE ADMIN OFF. THIS IS THE MOST IMPORTANT FEATURE (I WON A DISPUTE ON THIS PROJECT HERE ALREADY DUE TO THIS, THE PREVIOUS FREELANCER WAS UNCAPABLE OF FULLFILLING THIS REQUIREMENT !)
