Role Delegation not working for Time and Labor - View Time Cards

Summary:

Timekeeper A have delegated the Time and Labor Admin role to Timekeeper B via Roles and Delegations, but when the proxy/Timekeeper B tried to search/view the employee under Timekeeper A the search result display no data. Are there any process needs to run to enable the role delegation or did I miss extra step in order for Timekeeper B to search/edit the time card entry for other employee under Timekeeper A?

Steps I used:

Logged in as Timekeeper A/Supervisor A.

Delegated the T&L Admin role to Timekeeper B/Supervisor B.

Timekeeper A can search time cards under his/her employee.
