Telegram iOS app: In the βChatsβ tab, click the new message icon in the right upper corner. Select βNew Channel.β The main design elements of your Telegram channel include a name, bio (brief description), and avatar. Your bio should be: A vandalised bank during the 2019 protest. File photo: May James/HKFP. End-to-end encryption is an important feature in messaging, as it's the first step in protecting users from surveillance. The optimal dimension of the avatar on Telegram is 512px by 512px, and itβs recommended to use PNG format to deliver an unpixelated avatar.
