Howdy! Our organization has been implementing security through making custom groups and assigning application roles to the groups that fit the criteria for the reports that we built them in the past. It appears that when inspecting the permission for the oracle workbooks it has content duties assigned to them that are also being used by the custom groups that we assigned. This makes it accessible for the all the custom groups that we created that also share the application roles below to view the Oracle built workbooks and this would violate our security protocols.
My idea is that Oracle could develop a feature that could hide this folder from all consumer roles and only admin are able to see it, or just allow the permissions to be changed.
