Roles-based access control lets you restrict the target audience that is managed in admin roles in Hub Services. When you restrict the target audiences to a specific type of audience, admins are granted permission to send notification only to that target audience.
When an admin creates a notification in the Notification Builder, the Notification Builder only shows the target audience types and groups that are granted to this admin group. They can also view and take actions on notification sent to the custom target audience types.
When adding an admin group to a notifications role, you can select Organization groups, Workspace ONE Access User groups, Smart groups, and platform as target audience types. For each audience type, you can either grant admins full access to all members of that audience, or you can configure a custom access and select specific groups in the target audience that can receive notifications. For example, you can grant the global communications team Full Access to send notifications to all organization groups in your company and grant the United States communications team Custom Access to sending notification only to organization groups in the United States.

Prerequisites
Identify the user groups in the Workspace ONE Access services to assign to the admin roles.
