Adding an administrator

We go to our resource for mandatory subscription. Copy your bot's name into bot - t, namely login - @Your_BOT.
And paste it into the add administrators tab (see screenshot)

Adding to a resource via bot

You can also add the bot to your resource through bot management. To do this, you only need to:

1) In Telegram, go to the bot
2) Tap your bot’s name at the top
3) Then tap the "add to channel" button and select the resource

Done! The bot has been added to the channel/chat

Why are my friends’ contacts popping up?

It’s simple: you’re being offered to choose an admin from people you know, but we need a bot; click the button in the screenshot.

Final step of adding an admin to the resource

We assign the standard rights and save. Done
