how to access administrator work center for my hybris cloud for customer initial admin user?

1. I purchased an 3 month contract to tryout current Hybris cloud for customer and saw I'm having an admin user to start with, but how to customize my user to see more workcenters/business objects? I can't see administrator work center, nor business partner, nor service agent. How do I config the software?

2. I read about some articles of SAP C4C being supportive on OData services, how to enable that so I could check in real time the capability of SAP OData services.

Here's my order:
