Hi Folks This might be a stupid question But how do I add the support for Kotlin React JS (Web)? Do I need to add it to both top-level and inside common MPP module as well? Or just adding it to top-level would work?

Try to new a Kotlin/JS project by IDEA, then copy it to your KMM project. https://kotlinlang.org/docs/js-get-started.html

Thanks for the response 👍 Will try this.
