To avoid the usage of the app among some users and groups, admins can restrict the access to the product.
Admin configuration - global settings
Navigate to the global settings, to the Dashboard Hub section:
When “Restrict access” is enabled, only selected user(s) and group(s) will be able to access to the functionality. Thus, the rest of the users won’t be able to create, edit or remove dashboards i.e., no access to the interface of Dashboard Hub.
