Telegram Bot for Member Addition

I need a Telegram bot that can add members from public groups to my group.
Requirements:
- The bot should only draw members from public groups..
- No member verification is needed, so the bot does not need to handle any form of verification (Captcha, custom questions, etc).

Ideal Skills:
- Experience in Telegram bot development.


Please note, the bot should strictly adhere to Telegram's terms of service to avoid any potential issues.
