Starting with Ubuntu 17.10 the interface will be provided by an extension (shipped by default): https://github.com/ubuntu/gnome-shell-extension-appindicator Legacy tray icons have been completely removed in GNOME 3.26. By checking the interface, this will allow users of other distributions with GNOME to also use Telegram's indicator with the extension.
