When a user reaches the bottom of a Telegram channel and continues to drag upwards, an overscroll interaction is triggered. A green drawer slides up from the bottom of the screen, revealing a circular badge with an upward-pointing arrow. As the user pulls further, the arrow morphs into the avatar of the next unread channel, accompanied by its name and unread count, while the instructional text updates dynamically. Releasing the drag triggers a smooth slide transition that dismisses the current channel and loads the next unread channel.
