Pin
The Pin command allows you to pin a message in your Telegram group.
Permissions​
All administrators in your group and unified/ban operators can perform this command.
Syntax​
/pin
The Pin command doesn't have any kind of parameter or value. You can use it only as a reply to another message, wrote in the group by you, a bot or a member. You can't write a message as the command value and directly pin it using the command.
Examples​
I did an important announcement in the group with a message. It can be whatever you want, a text message, a photo or a video. To pin it, simply use the "Reply" function and write:
/pin
Yes, it's this easy.
