No themes integration for qt/KDE apps on MX 23

Hello everybody,
I am using MX 23 with Xfce 4.20. Sadly some qt apps are not integrated with the system (i.e. Strawberry is, Okular is not).
I tried exporting the QT_PLATFORMTHEME=qt5ct, and apparently it's properly set:

$ env | grep qt

Re: No themes integration for qt/KDE apps on MX 23

You could try posting this on the MX Forum, where the very helpful MX Devs will see it...

MX-23 (based on Debian Stable) with our flagship Xfce 4.18.

Re: No themes integration for qt/KDE apps on MX 23

Did you use the utility to adjust the settings and choose a theme. You may nee to install some themes to match what you have in Xfce4. The results aren't perfect but you can get close.
