Don't know Android, so could be completely wrong here.
This channel is for support of the
https://github.com/kotest/kotest testing library, and not something that is built into the Android libraries.
If I'm correct, and this isn't related to the Kotest library, then a generic channel like
#test or
#android may be a better place to ask.
If I'm wrong, then one of the devs, or another user, will be along to help you.
