To pre-approve people or a person to a management role, using the PBAC membership policy, we need to follow the below steps
Add a PBAC attribute to a person - PBAC field type or an attribute is a connector used to connect an EmpowerID actor like a person to a PBAC membership policy target such as a management role.
Create a PBAC membership policy (of the type pre-approve) for a management role - It is required to create a PBAC membership policy so that we can use it for a target type( e.g., a management role).
Add the same PBAC attribute to the policy - PBAC field type or attribute should be added to a PBAC membership policy, for connecting it to an EmpowerID actor.
Wait for policy compilation and verify the result - Once the policy is compiled the person will be pre-approved to the management role
