Hi. 👋
I'm trying to write a basic "Hello World" type app that can run on Android, iOS, Desktop, and Web.
I am following this guide...
https://www.jetbrains.com/help/kotlin-multiplatform-dev/quickstart.html
Given that I'm developing on 🪟, I did the web KMP wizard which seemed to work well enough.
Without much fuss, I have it running on Android and I next wanted to try Desktop but I ran into a problem.
The tutorial suggests that there will be a composeApp [desktop] run configuration but I don't see that.

I only have a single run configuration called composeApp which works to launch the Android build.

Maybe a higher level view is better...

So you can see the composeApp configuration under an Android App folder. I guess I'm wondering if I should create a new Desktop App folder with a new composeApp run configuration under there. 🤔

When I try to add a new configuration, I get prompted with quite a few options and I'm not really sure which one equates to "run this as a Desktop App".

Maybe Application?

there is a #C3PQML5NU channel, maybe they can help you 🤞

I think I figured it out. I noticed that the web tutorial had the little Gradle 🐘 mascot in the run configuration for both the Web and Desktop builds. So I selected that one from the long list in the screenshot above and...

I will say that the build spit out some warnings/errors...

but it ultimately ended with webpack 5.94.0 compiled successfully in 10046 ms and the app runs in a browser.
