We plan to get some redemption codes from ABM to our partners to download custom apps, and they will use their own devices. But there is a problem, if they are not involved in this business anymore. If user downloads a custom app to their own device using redemption code, is there a way to force remove it from the App Store purchased list? Is there a way to force remove it from the App Store purchased list? Or can only add permission verification to the application?

I know that I can get multiple redemption codes from Apple Business Manager, let users download custom apps using redemption codes, and there are region restrictions. Does the user have to enroll own devices in MDM to download custom apps with redemption code? Because users are not necessarily full-time employees of the company, they may also be short-term partners who use their own devices.
