Custom distribution of enterprise apps that require communication with the with an MDM API

Looking for someone with experience in custom app distribution - submitting enterprise apps that require MDM API communication to Apple for review

  • How does Apple run these apps. Do they have access to a testing instance of the MDM?

  • Do they put the device that is running the app under MDM supervision?

  • If the app requires a managed app configuration file that is configured in the MDM does Apple do it?

Thanks
