In our last release we introduced a new and much easier way to manage system-wide permissions and monitor permissions for operator groups. In the current release we have implemented the same approach for individual operators.
We recommend assigning permissions on the (operator) group level. In most situations you will have teams within your organization that should have the same set of permissions. It is easier to set up teams than repeating the same steps for each individual. However, there may be exceptions and that is why you now can assign permissions to individual operators in the same easy way as to operator groups.
