Content (please ensure you mask any confidential information):

We’re looking to enforce attachment requirements in the Identification Info section of Oracle Fusion HCM. Specifically, we want to make it mandatory to upload supporting documents when users add, update, or delete records related to:

• Citizenship
• Visas and Permits
• Passports etc

Has anyone implemented this kind of validation? Is there a way to configure this through page composer, HCM design studio, or a sandbox rule? Any guidance or best practices would be appreciated.
