1 - Ensure that you have the latest Intune Powershell SDK installed:

                 From PS Admin:  


Install-Module -Name Microsoft.Graph.Intune


2 -  Consent to the MS Graphic API   (this should only need to be done once more tenant)


Connect-MSGraph -AdminConsent


3 - Connect to MS Graph


Connect-MSGraph


4 - Run GET-DeviceManagement Script


You will need to download / create a PS script to perform this function - the one attached here was downloaded from Github on 6/28/22 - mc (file attached to this article)
