Get all Enterprise Apps and add at least 2 owners with PowerShell

Following the script from Vasil Michev I came across:
https://www.michev.info/blog/post/5940/reporting-on-entra-id-application-registrations

When the script has run the output will probably show that there are a number of Enterprise Apps that haven't got an owner associated to them.
This can become a problem when trying to identify it's usage, and when a secret or certificate is almost expiring or has expired.

To make sure you have your owners set, I created this script.

It get's all Enterprise apps and filters the ones without an owner. It then add the owners you want to all the apps that haven't got an owner.

Remember to test this out first.
