Open link

A button that opens a link: a website, a channel, another bot, a file.

How to set it up

Add a button under a message, pick "Open link" and give the address. You can pick your channel or bot from the list, and use variables in the address.

"Channel boost" opens the boost window of the channel you pick. Only people with Telegram Premium can boost.

These buttons exist only under a message, not in the menu under the input field.
