Channel Username
The unique public handle of a Telegram channel (e.g. @example).
A Telegram channel username is the unique public identifier preceded by '@' (e.g. @cointelegraph). Usernames allow anyone to find and join the channel via t.me/username links. Usernames must be 5–32 characters, containing only letters, numbers and underscores. A good username is memorable, matches the channel brand, and is easy to type.
