New-MgBetaGroupSetting not working

[AlyaKoni]

Describe the bug

Trying to create a new Group Directory Settings:

# Checking team guest settings
Write-Host "Checking team guest settings" -ForegroundColor $CommandInfo
$SettingTemplate = Get-MgBetaDirectorySettingTemplate | Where-Object { $_.DisplayName -eq "Group.Unified.Guest" }
$Setting = Get-MgBetaGroupSetting -GroupId $Team.GroupId | Where-Object { $_.TemplateId -eq $SettingTemplate.Id }
if (-Not $Setting)
{
    Write-Warning "Setting not yet created. Creating one based on template."
    $Values = @()
    foreach($dval in $SettingTemplate.Values) {
	    $Values += @{Name = $dval.Name; Value = $dval.DefaultValue}
    }
    $Setting = New-MgBetaGroupSetting -GroupId $Team.GroupId -DisplayName "Group.Unified.Guest" -TemplateId $SettingTemplate.Id -Values $Values
    $Setting = Get-MgBetaGroupSetting -GroupId $Team.GroupId | Where-Object { $_.TemplateId -eq $SettingTemplate.Id }
}

This gives the error:
