As of right now, Android Studio and IntelliJIDEA do not support previewing composables in commonMain. You could create a preview in androidMain and see the previews that way. The Compose Multiplatform previews are currently only supported in Fleet. I assume the preview feature is coming (but have no concrete proof), as JetBrains have recently announced that they're shifting from creating a standalone KMP IDE to providing better Multiplatform support in the IntelliJ IDE.
