Hybrid frontend project with Kotlin JS and manually written JS

So, the idea would be to make the Gradle module with the data model code also target js(IR) and create an NPM library via binaries.library() like you’ve also described here, and then have another (pure JS?) module in Gradle that depends on that NPM library to implement the frontend. Correct?

But what would be the workflow for a Kotlin developer to contribute to the frontend module then?
