Hello sir, I have already a script in which you can scrape members and add to your group so I show you demo first and provide script in 5 minutes within budget. Let's discuss more over chat.
Thank you
pls look my profile once
Check out my bot - @TGScraperBot.
It can scrape members from public and private groups, scrape members which sent messages into group chat, filter members by recent activity.
Feel free to contact me anytime.
