Okay, more headway made. I finally realized that I needed a new class (PropList) to hold the list and the current value for the object. I have not yet been able to get the Combobox to display the list or current value. The DataTable is created properly, with the column for the List type created as a PropList type. Then in the Window the DataGrid's ItemsSource is set to the ViewModel's property for the DataTable. All the columns fill with the correct values, except that PropList column. One of the solutions I found in my searches says that adding this to the XAML should fix it:

Where CurrentValue and Values are the 2 properties of PropList. Then include this in the code behind for the AutoGeneratingColumn event:
But something is still amiss and I am at a loss on where to look.

Anyone ?

Do you need to use MS Graph?

With MS Graph you would have everything. From device info, who they have lunch schedules with, and Sally’s next fingernail appointment

It seems to be able to access the api you need to register your 'app' then you can have at it.
https://learn.microsoft.com/en-us/graph/auth-register-app-v2

Do you need to use MS Graph? If not you could build your own simple web server on the company intranet or host it in the cloud. Something like Go with SQLite db would be easy enough to setup, you could even register it and then use it with the MS Graph api to get extra data if needed.
