WHY IT NEEDS A POLICY

Why cancel_change_approval needs a policy

Cancelling an approval modifies the state of a change request in the ITSM system. While this is a significant action that could disrupt change management workflows, it is generally reversible (the approval can potentially be re-initiated), placing it in the Write category rather than Destructive. The blast radius is medium as it could block or disrupt legitimate change processes.
