There has been a new functionality added to Plasma 5.25, namely long-press acting as right click on touchscreen tablet pc. On my latest Debian-sid install, this functionality is fully working with Dolphin. However it does not work with Okular (version 22.04.03). This functionality is pivotal, at least for two reason: On a tablet pc, once you've added an annotation you have no way to delete it, since it requires a right click on the annotation. Also, you can't leave fullscreen mode as described here: https://www.reddit.com/r/kde/comments/u3fm2x/getting_out_of_okular_full_screen_mode/ SOFTWARE/OS VERSIONS Linux/KDE Plasma: debian-sid plasma 5.25 kwin-wayland okular 22.04.03

It was added to the Plasma desktop and Task Manager; rather than being a universal thing. Every app that wants long-press to turn into right-click needs to implement it on its own. Dolphin and Plasma have, so this is a request for Okular to do it too.
