â€error_codeâ€:403,â€descriptionâ€:â€[Error]: Forbidden: bot is not a member of the channel chat
Now all clients allow to do it, but it’s not pretty simple.
In any Telegram client:
1. Open Channel info (in app title)
2. Choose Administrators
3. Add Administrator
4. There will be no bots in contact list, so you need to search for it.
5. Enter your bot’s username
6. Clicking on it you make it as administrator.
