Get-IntuneDeviceConfigurationPolicy returns only some of my policies

What happens when you run this script? It shows me the stuff the other command didn't showed me

#oauth token
$clientId = "d1ddf0e4-d672-4dae-b554-9d5bdfd93547"
$redirectUri = "urn:ietf:wg:oauth:2.0:oob"
$resourceURI = "https://graph.microsoft.com/"
$authority = "https://login.microsoftonline.com/common"
$AadModule = Import-Module -Name AzureAD -ErrorAction Stop -PassThru
$adal = Join-Path $AadModule.ModuleBase "Microsoft.IdentityModel.Clients.ActiveDirectory.dll"
$adalforms = Join-Path $AadModule.ModuleBase "Microsoft.IdentityModel.Clients.ActiveDirectory.Platform.dll"
[System.Reflection.Assembly]::LoadFrom($adal) | Out-Null
[System.Reflection.Assembly]::LoadFrom($adalforms) | Out-Null
$authContext = New-Object "Microsoft.IdentityModel.Clients.ActiveDirectory.AuthenticationContext" -ArgumentList $authority
$platformParameters = New-Object "Microsoft.IdentityModel.Clients.ActiveDirectory.PlatformParameters" -ArgumentList "Always"
$authResult = $authContext.AcquireTokenAsync($resourceURI, $ClientID, $RedirectUri, $platformParameters)
$accessToken = $authResult.result.AccessToken

$apiUrl = 'https://graph.microsoft.com/beta/deviceManagement/deviceconfigurations'

$Data = Invoke-RestMethod -Headers @{Authorization = "Bearer $($authResult.result.AccessToken)"} -Uri $apiUrl -Method get
$data.value

THe script I posted is connecting to the beta and shows it all, but the msgraph is connecting to the v1.0 

So if you want the get-intunedeviceconfiguraitonpolicy to connect to the beta:

Update-MSGraphEnvironment -SchemaVersion beta

connect-msgraph
