How to create multiple domains or projects in Orchestrator


We have around 45 robots for scheduling in Orchestrator. Currently they are accessible by everyone.
We would like to know is it possible to create/split into multiple domains/projects so that we can divide the robots as per the grouping.
Ex: Group1/Project1 -> Robots1-15
Group2/Project2 -> Robots 16-45

Project2 people should not have access to Project1 and vice versa.

Is it possible to create the above requirement?

We need it urgently, kindly help ASAP.
