Guideline 3.2 - Business
We found in our review that your app is intended to be used by a specific business or organization, including partners, clients, or employees, but you've selected public distribution on the App Store in App Store Connect. Since the App Store is intended for apps with a public audience, we recommend reviewing the other distribution options available to you through your Apple Developer Program Account.
