Adding Approvers to Contract PDF Document After Approval

In Oracle Fusion Procurement Contracts, once a contract goes through the approval process, the generated PDF does not display the approval history or the list of approvers.

Is there a way to add the approvers (with their names and approval dates) to the contract PDF document after the approval is completed, so that this information is visible to the signer and can fulfill our internal governance requirements?

If this requires customizing the seeded ContractDataModel.xml, what is the recommended approach to achieve it while staying aligned with Oracle best practices?

Thank you,
Khalid
