AC10 Access Request Management and provisioning with CUA

We are starting to implement Acees Request Management. We have CUA in place. We will assign roles to users

from AC10 to selected systems. At this stage CUA remains for not selected systems. I have not found any

documentation how to set up this.

Do we need GRC plugin installed to CUA client?

Do we need to configure CUA connector to AC10?

Is AC10 taking care of provisioning to CUA and selected clients? So that CUA is in sync with CUA child clients.

Thank you in advance!
