Add application permission support to Delete AAD devices. This is currently not supported when used with application authentication: https://docs.microsoft.com/en-us/graph/api/device-delete?view=...
Guess that we will have to switch back to using the AzureAD module, until Microsoft kills its API layer. Then we will have to switch back to typewriters.
I am also affected by Update-MgDevice not supporting Application identities.
