(Updated/Resolved) Data security implementation for candidate pools in 23B

Update 30 May, 2023: This instruction has been added to the 23B Release Readiness documentation

To support data security for candidate pools and allow some roles to view, report, or select all pools, a new aggregate privilege has been introduced in 23B: Manage Candidate Pool. This privilege contains both the existing functional privilege and the new data privilege. While the seeded roles Hiring Manager and Recruiter have been adjusted accordingly, custom roles containing only the functional privilege Manage Candidate Pool will need to be adjusted to get the aggregate privilege under the role hierarchy. The functional privilege alone is no longer sufficient, the aggregate privilege Manage Candidate Pool is now required.
