Is it possible to write a bot on telegram-api that could subscribe to public channels in Telegram?

Question

Node.js

The task is to write a bot that would subscribe to a public channel at the user's command and, at the other command, repost messages from the channel to a chat with the user. Can Telegram bots subscribe to channels?

Answer 1

No, bots cannot enter channels and groups on their own.
In the case of channels, only an administrator can add a bot to a channel.
