An existing vRealize Operations user has been granted the Administrator role.

According to the vRealize Operations documentation, the Administrator role includes privileges to all features, objects, and actions in vRealize Operations, including creating and managing dashboards1. Therefore, if a user has been granted the Administrator role, they can create dashboards regardless of any other roles they may have. The ReadOnly role does not prevent the user from creating dashboards, as it only limits their access to read operations1. The ContentUser and DashboardManager roles are not required for creating dashboards, as they only provide privileges to manage specific content types1. References: 1: Roles and Privileges in vRealize Operations - VMware Docs(https://docs.vmware.com/en/vRealize-Operations/8.10/com.vmware.vcom.core.doc/GUID-9F316466-FACA-4DA0-8F3E-51BC73793990.html)
