I need to build a Telegram marketing tool that does the following functions.
1. Scrapes usernames from channels/groups, and allows for export of this list to CSV.
2. Auto-adds (imported CSV) to preferred channel or group.
3. Allows bulk send messaging.
The marketing tool can be built on any language as long as it's fast. I have a 24 hour deadline for this project so if you can't code it in 24 hours I'm not interested.
