Hello Sir,
I have worked before on Telegram Automation, Scraper, Bot and Web Browser automation, I believe I have the right skills to make the best of your project.
It is 100% possible to make this type of automation without needing to you add a bot to the channel or being admin, only your normal user account.
Maybe you could send me a message so we can chat more about your project requirements?
Maybe I can provide a FREE demonstration for you project.
Thank you for your time, have a good day!
