Is it possible to add QubesOS service utils to Dolphin?

I’ve been using QubesOS for a short while, and have recently wanted to move to using KDE plasma (or, at the very least, hyper minimal sessions with the bare minimum to emulate the feel of using KDE plasma, like I’m used to).

I’ve gotten everything to work in terms of theming, and I have been able to install/use my desired applications, but I haven’t figured out how to get QubesOS service utilities to work with dolphin. Pretty much just the last thing on the bucket list asides setting default applications, which should be a bit easier to do.

I’ve tried installing the qubes-core-agent-nautilus package to my template out of (slight) desperation, but no dice.

I also didn’t find any relevant packages for dolphin specific service utilities, so I’m assuming that either I’m just glossing over something, or that it’s going to be a bit of an intensive process?

Either way, I still need to do it, as I use dolphin across all of my other linux systems (and KDE plasma as well, which is why I made the switch), so having to learn a new workflow when I’m already satisfied with my main workflow would be a bit jarring.

Has anybody been able to do this before? If so, how would I go about doing it for my system?

So I pretty much already have a KDE template already made. I ended up using the Fedora-44-Minimal template and I installed the bare minimum for a functional X-session environment. I did use this, and a response in a different forum to add the .desktop icons. Apparently, they’re in /usr/share/kservices5/ServiceMenus/, but they were missing their mime types, which I set to all/all;, and that fixed that issue. I might end up adapting to use the Debian 13 template method, but I did want Fedora as the base for more recent packages (as I sometimes code on my system, and I want relevant packages for that application), as well as SELinux support (although that seems unnecessary with QubesOS).

I do have to ask, though: does this method make everything truly run as KDE-Plasma, or does it merely just leverage an X-session like the minimal template does, while applying similar functions as the legitimate desktop?

Additionally, is it possible to mask unrequired packages with apt? I, sadly, don’t have much experience in fine-grained package management on apt-based systems, but I want to minimize my package count (and attack surface) by removing anything not necessary for my system to run properly in a KDE-Plasma environment.

Thanks for the initial reply by the way, much appreciated advice.
