STEPS TO REPRODUCE
1. start Wayland session
2. open Task Manager settings
3. click on "Behavior" in the left side
4. open "Clicking grouped task" combobox and choose "Shows 'Present Windows' effect"

OBSERVED RESULT
As we can see in the attached screenshot, an inline message says that Present Windows is not enabled/available. But Present Windows effect works when I move cursor to upper left corner of my screen.

EXPECTED RESULT
Present Windows effect should work with Task Manager on Wayland

SOFTWARE/OS VERSIONS
Operating System: KDE neon Unstable Edition
KDE Plasma Version: 5.19.90

That's odd. Cannot reproduce on X11.

Well that's not surprising, it's announcing itself through an X atom.

See kwayland-integration integration of the KWindowSystem backend

windoweffects::isEffectAvailable

The implementation of presentWindow is also ... somewhat missing, so the warning isn't entirely wrong in the current state.

Patch will be somewhat involved as it means patching:
 - kwayland-protocols
 - kwayland-server
 - kwin
 - kwayland-integration

Would be a good JJ for someone wanting to do their first wayland protocol.
