Zooming with touchpad seems to be not available at all, also tested with 23.04.3 from flathub (can't test with the kdeapps remote as I can't access it anymore for a few days now). Only tested with PDF on Gnome environment using Wayland. For creating a backtrace I've installed libokular5core10-dbgsym and okular-dbgsym, this is the output: gdb -batch -n -ex 'set pagination off' -ex run -ex bt -ex 'bt full' -ex 'thread apply all bt full' --args okular This GDB supports auto-downloading debuginfo from the following URLs: <https://debuginfod.debian.net> Enable debuginfod for this session?

Indeed, the feature hasn't been implemented yet.
Interesting. I wouldn't have guessed something like this could be missing in 2023. Is there a way to mark this as feature request then?
I changed it to "wishlist" already to reflect that.
Vote for this feature request. Zooming with touchpad is indispensable for laptop. I think this should be a high priority on the wishlist. Please at least implement this in Wayland.
