    $policyItem1.ValueSecretId = 54
    $policyItem2 = Get-TssSecretPolicyItemStub -TssSession $session -ItemName AssociatedSecretId2 -ApplyType Enforced
    $policyItem2.ValueSecretId = 65
    New-TssSecretPolicy -TssSession $session -Name 'Policy - Associated Secrets Enforced' -Active -PolicyItem $policyItem1, $policyItem2
