 We focus on four basic interactions:
 
-1. The SME uses the End-User API to manage their certificates.
-2. The EDC tenant is connected to a partner's EDC in the dataspace for data sharing (provisioning & consumption).
-3. The MPS tenant has a connection to the EDC tenant for configuration purposes (e.g., initiate setup, onboarding information).
-4. The MSP tenant realizes the technical onboarding flow.
