@James Chan_110, Thanks for posting in Q&A. Currently, the app type we can deploy to macOS are Microsoft 365, Microsoft Edge, LOB, web clip and Microsoft Defender for Endpoint app. For MacOS App store app, it is not integrated with Intune. If you want to deploy store app to MacOS, you can try VPP using ABM or ASM.

To get MacOS store app type, you can feedback to Apple MDM to see if we can have this in the future.
Thanks for your understanding.
