How to build a Job requisition approval rule based on Job DFFs

Hello,

We are configuring Job Requisition Approval Rules in Oracle Recruiting Cloud.
When we try to build conditions based on attributes, we can see fields from Requisition Fields and Position Details, but we cannot find any of the Job DFFs (Descriptive Flexfields) that we have configured at the Job level.

Our requirement is to use a Job DFF value as a condition in the Job Requisition approval rule.

Could you please confirm if it is possible to expose and use Job DFFs in approval rules for Job Requisitions?
If yes, what setup or configuration steps are needed to make them available?
