I have a question about an APP registration/recovery: We have an App that uses Graph and EWS Microsoft 365 APIs. Customers can use our tenant registration but once we have distributed the app, we are concerned about losing/damaging the AppID in the future (affecting thousands of users).
What is the process to backup the AppID and its settings, and to restore the same AppID?
You can restore application by using application object id using PowerShell
