touchscreen settings to pan/zoom/rotate

Hi Everyone.
I have a touchscreen, running xfce4 and using Gmocappy 3.1.3.8 with pleasure. Does anybody knows how to setup the touchscreen so that I can use all three preview functions, moving around (works already), zooming, and rotating? Is it possible to emulate mouse buttons somehow, e.g. long press, two finger press, etc.?

Thank you!

To use those features you would have to use latest GNOME desktop environment or install POP!OS.
See how to install GNOME on Debian, should be fairly easy, but beware that it might break the installation.
