22D - Roles and Delegation tile is blank for custom Line Manager role

Summary:

Hi All

We have found an issue whilst testing 22D. When we try to access the Roles and Delegation tile via Me, Roles and Delegation as a custom line manager, we get a blank page. Our custom Employee role is ok and can access this tile normally. Testing with the seeded line manager role, the tile can be accessed as expected. Does anyone know what privilege/duty gives permission to this tile?

Currently I'm adding in the new line manager duty roles and privileges one by one to our custom line manager role. However, they all look unrelated so not sure if this is going to work.
