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.

But it's all right, when you're all in pain and you feel the rain come down
It's alright, when you find your way, then you see it disappear
It's alright....
