Other fields of EmpAssignment Info Not showing in HCM Adapter Atom Feeds

Summary:

We want to leverage Atom Feeds using OIC for EmpAssignment. However, I noticed that the the level of info I am getting in HCM Adapter is not the same as what I get through REST API service. The AssignmentExtraInfoId and flexfields are not showing in the HCM Adapter as part of the response.

Content (required):

From POSTMAN Which shows the DFF FIELD
