Approval workflow for delete contact from family and emergency page

Summary:

Hi Team,

We have configured the approval rule to be triggered when employee delete the contact from family and emergency contact.

We tried using the below rule

((Task.payload.Current Person ContactRelationship.result != null) AND (Task.payload.Proposed Person ContactRelationship.result == null)) but not working.

We already have a rule for contact as below

(((transactionApprovalRequest.ViewInstanceName == "QuickContact") OR (transactionApprovalRequest.FamilyOrEmergencyContact == "Y")) AND (transactionApprovalRequest.SelfServiceTransaction == "Y"))

But its not working for delete contact.

Please suggest.
