Deprecation warning "expect and corresponding actual are declared in the same module, which will be prohibited in Kotlin 2.0"

[fwilhe2]

I'm getting this deprecation warning in vs code:

Property 'secondElement': expect and corresponding actual are declared in the same module, which will be prohibited in Kotlin 2.0. See https://youtrack.jetbrains.com/issue/KT-55177

Not yet researched how to do it properly in kotlin 1 and 2, but opening this issue because I think this template should not produce warnings by default.
