Microsoft 365 License overview per user

There are many licenses you can add to your 365 tenant, but it's difficult to get a good overview of all users with their assigned licenses and what each license plan contains. I wrote a PowerShell script for that, it outputs all the users with their assigned SKU (Short for Stock-Keeping-Unit, but in Microsoft terms a license SKU predefines all the properties of a license, including Product/Version/Features) in a CSV file.
