What must be done for Internal Salesforce users to access the Salesforce CMS app?

For internal Salesforce users to access the Salesforce CMS app, it is essential that the app is set to 'Visible' in their user profile. This setting determines whether users can see and access the app within their Salesforce environment. If the app is not marked as visible in the user’s profile, even if they have appropriate permissions or if the app is available in the system, they would be unable to access it. User profiles control access to applications, ensuring that only authorized individuals can interact with certain functionalities based on their roles within the organization.

In contrast, simply adding the app to their favorite apps does not grant access; it merely provides a shortcut for users who can already access it. Publishing the app publicly is not relevant for internal users, as their access is managed through their profiles rather than public visibility. Similarly, while defined permission sets can grant additional access rights, the fundamental requirement for visibility must be established in user profiles first. Thus, the correct approach involves ensuring that the app is marked as visible in the relevant user profiles.
