Configure one app per department and activate record pages for each app is how the administrator should ensure this is configured correctly. An app is a collection of items that work together to serve a particular function for a group of users. An app can include items such as tabs, objects, reports, dashboards, and record pages. A record page is a type of Lightning page that displays details about a specific record. A record page can be customized using Lightning App Builder and activated for different apps, profiles, or record types. By configuring one app per department and activating record pages for each app, the administrator can ensure that the backup team users can view records in a way that makes sense for each department depending on which app they are using.
