I searched Google and a 2-year-old post said that it was currently not possible to customise them. After all these years, is it still true in 6.0 Wayland? Do Plasma developers have any plan to allow customise them natively in System Settings?
I don’t want to use Fusuma or something. I had tried to use it under Gnome years ago when Gnome had no native gestures, and it was not the smooth gesture experience I expected. It felt more like trying to enable gestures using a third-party software under Windows 7.
