I'm in a similar situation and I simply did the multi-platform setup, but with the only target being JVM. I tore out anything else unrelated to desktop.

I'd still be curious to hear any other more "official" answer

The template is now moved to a website <https://kmp.jetbrains.com/>
I remember used to see a news said that  the template will come back to idea in future version soon.

In the wizard you can just choose only desktop. I’ve used it quite a bit. It will only create a desktop app. For documentation it’s a bit scattered yes. I’ve mostly learned by doing things, sometimes the documentation from android works fine for compose elements since they are mostly the same, sometimes you need to look a bit further.

<@U10EJRH2L> what build system does your existing project use? Is it on Gradle?

Then you should be able to use the setup wizard to create a sample project for only desktop, look in the Gradle config files for Gradle plugins and project dependencies, and add those to your existing project's Gradle config
