Running KDE Plasma apps in Cinnamon

Hello

I was looking for an SVN GUI, I used PySVN Workbench in 19.3 but it seems to be gone in 20.

I saw that KdeSVN was still available, I used to really like that some years ago.

So I installed it but it shows up with no icons:

I played around a little bit, even installed kde-full, nothing works. And I found that the same seems to be true for /every/ KDE app. All of them are missing the icons inside (on menus, buttons, etc).

If I log into Plasma - all the apps' icons look fine.

Is it possible to get KDE apps to look properly when running Cinnamon? Is there perhaps some service I need to run to get them to show up?

Thanks in advance.
