RecoverPoint - Powershell script - Query thru vCenter - Permission

Hi

 We have a Powershell script that need to only query (Get) RecoverPoint API (groups, alerts, replication, licenses).

We have created a user in vCenter and gave him ReadOnly permission since we are trying to give the least privileges required to query.

We connect with the Powershell command  Connect-ViServer and we are able to login to the vCenter.

The problem occurs when we query the RecoverPoint API with vCenter ReadOnly permission, we get a error : User has insufficient privileges. We understand that the ReadOnly permissions is not enough.

We know that when we set the user in vCenter with admin permission, we can query RecoverPoint API.

So the question is, is there a way to give less privilege to the vCenter account and be able to query RecoverPoint API ?

Thanks
