Remove stale devices from Azure AD using Micrsoft Graph powershell SDK

Question

How can I remove stale devices from Azure AD using MS graph PowerShell module?

Trying with {Device.ReadWrite.All, Directory.ReadWrite.All} scops, even Get-MgDevice show the following error

PS C:\WINDOWS\system32> Get-MgDevice -DeviceId 91140dae-dc4a-4c72-aba2-ea2a391747a9 Get-MgDevice : Resource '91140dae-dc4a-4c7288888' does not exist or one of its queried reference-property
objects are not present.

Answer 1

OK. I figured it out if anyone is interested:

# Delete Azure AD devices older than 120 days
$dt = (Get-Date).AddDays(-120)
$jt = "Workplace" # Join Type

$Devices = Get-MgDevice -All:$true | Where-Object {($_.ApproximateLastSignInDateTime -le $dt) -and ($_.TrustType -eq $jt)}

foreach ($Device in $Devices) 
    {
    Remove-MgDevice -DeviceId $Device.Id
    }
