Script explanation

The script can be used directly without any modifications. The admin will be asked about the expiration date and whether they would like to see already expired secrets or certificates or not.

The "Add-Member" command is responsible for creating the columns in the CSV file. You can modify the "$Path" variable directly in PowerShell, with a CSV file path, in case you'd prefer the export to be non-interactive.

Command Notes
Get-MgServicePrincipal Retrieves an enterprise application from your directory.
Get-MgServicePrincipalOwner Retrieves the owners of an enterprise application from your directory.
