I found a boat load of messages that were posted to
#kotlin-native which are related to Compose, but not Kotlin Native (here is an example:
https://kotlinlang.slack.com/archives/C3SGXARS6/p1670750089070259 ). Some Compose channels exist but there isn't one that covers general Compose stuff. Confusingly
#compose covers JetPack Compose instead of general Compose stuff. Other Compose channels exist like
#compose-desktop for example. It appears as though no standard naming is applied to the various Compose channels that exist in the Kotlin Slack.
