Azure AD PowerShell for Azure Resources in PIM

Have you wondered how to user Azure AD PowerShell for Azure Resources in PIM. This is a little tricky since the id's in OData do not support slashes but the id's for Azure resources contains slashes. Hence the id for these resources are mapped to a GUID in Graph.
To query the azure resources in Graph, you will need to pass an ExternalId filter and the rest should be straight forward.
Below is an example of adding a user as Eligible Owner on a subscription.

The pre-requisite is that you have already installed Azure AD Preview PowerShell by following these steps

$resource = Get-AzureADMSPrivilegedResource -Provider azureResources -Filter "ExternalId eq '/subscriptions/38ab2ccc-3747-4567-b36b-9478f5602f0d'"
$roleDefinition = Get-AzureADMSPrivilegedRoleDefinition -ProviderId azureResources -ResourceId $resource.Id -Filter "DisplayName eq 'Owner'"
$subject = Get-AzureADUser -Filter "userPrincipalName eq 'upn'"

$schedule = New-Object Microsoft.Open.MSGraph.Model.AzureADMSPrivilegedSchedule
$schedule.Type = "Once"
$schedule.StartDateTime = (Get-Date).ToUniversalTime().ToString("yyyy-MM-ddTHH:mm:ss.fffZ")
$schedule.EndDateTime = (Get-Date).AddDays(30).ToUniversalTime().ToString("yyyy-MM-ddTHH:mm:ss.fffZ")

Open-AzureADMSPrivilegedRoleAssignmentRequest -ProviderId azureResources -Schedule $schedule -ResourceId $resource.Id -RoleDefinitionId $roleDefinition.Id -SubjectId $subject.ObjectId -AssignmentState "Eligible" -Type "AdminAdd" -Reason "Test"
