Hello!
I read your project description. I have been working with social media and API, especially Telegram, for more than 1.5 years. In this time I have created over 12 different Telegram scripts for different purposes, from simple to complex. Video uploading with a Telegram bot to a channel is quite possible and I can modify the script to selection, upload, quantity and time according to your needs. In fact, I have previously worked on a Telegram bot where many photos and video were required to be uploaded.
With my previous experience with Telegram, I can confidently say I can create, modify a script that meets all of your needs and make it work just how you want it. I am very much looking forward to hearing more details from you. Hope you hear from you soon
Best Regards
Sakib
