Get all Intune policies using PowerShell and Graph API

This looks very useful but I get an error when installing the IntuneStuff module.

"Import-Module : AzureRM.Profile already loaded. Az and AzureRM modules cannot be imported in the same session or used in the same script or runbook."

I've found that the AzureRM module is an older module, but I cannot uninstall it because it is a dependency of IntuneStuff.
