When there is an unread message, the chat window should be marked “urgent” so that explorer’s taskbar (or any given linux wm) can react as appropriate.
“Urgent hint” is what X11 called it. Wayland eventually adopted support, though it apparently required months (years?) of persistent complaints that notifications alone are not sufficient.

Windows seems to refer to it only by “window flashing”.
This is an old, established, and common feature that everyone will have seen having used any desktop OS, so I assume it is not necessary for me to thoroughly describe this in detail- but I will provide screenshots.

Optional: if it’s trivial to do, why not also support the Windows taskbar thing where it shows a number badge like so:
Thanks!
