It sadly doesn’t quite work right on KDE. You can get close: you can show an application launcher, or a exposé-like window overview, or a pager, but you can’t show all of them at once in a way that’s easy to work with between like Gnome does.
Heck, even Gnome regressed Gnome 40, as you don’t get the vertical desktop overview any more. At least there’s shell extensions that let me get Gnome 3’s behaviour back.
It’s a real pity, because I like KDE, and definitely the KDE apps, more, but the Super-key overview is no hard to quit.
As a slow cyclist, I’d totally wear this.
