Contingent (Recruiter) Workers Unable to Access Recruit-to-Hire Dashboard Security

Summary:
What hidden security role or privilege grants access to the “Recruit to Hire Dashboard” function?

Observation:
When I assigned the following seeded roles, the Recruit to Hire Dashboard became available for a recruiter (contingent worker):

• Contingent Worker – PER_CONTINGENT_WORKER_ABSTRACT
• Recruiter - View Non-Confidential Data – RECRUITER_-_VIEW_NON_CONFIDENTIAL_DATA
• Employee – PER_EMPLOYEE_ABSTRACT

However, per policy, a Contingent Worker cannot be assigned the Employee role. Once I removed the Employee role, the Recruit to Hire Dashboard disappeared.

I reviewed all the relevant security roles but could not find any documentation about the privilege behind this function. I would appreciate your guidance in identifying the correct role/privilege.
