An advertiser has an employee who wants to create and edit campaigns. The advertiser does not want the employee to access billing and business settings. Which permission should the advertiser give this employee?

The Campaign permission level allows an employee to create, edit, and manage campaigns without accessing sensitive financial or business settings. This aligns with the advertiser's need to grant campaign management capabilities while restricting access to billing and overall business configurations. Audience permission would only allow managing audience lists, not campaigns. Admin permission grants full control over all aspects of the account, including billing and business settings, which is explicitly what the advertiser wants to avoid. Analyst permission typically provides view-only access to reports and analytics, not the ability to create or edit campaigns.
