The message of rejection is:
Guideline 3.1.4 - Business - Payments - Content Codes
Your app enables additional features or functionality when used with augmented reality markers or QR codes. However, those features are not available in the app to users without the necessary markers.
Next Steps
To resolve this issue, please provide a means to access these features from within the app, such as through achievements or in-app purchase. If they can be freely obtained, such as through a link to a website, please revise your app to include clear instructions for obtaining the necessary markers or codes.
Please note that apps cannot require users to purchase unrelated products or engage in advertising or marketing activities to unlock app functionality.
Request a phone call from App Review

Guideline 4.2 - Design - Minimum Functionality
We noticed that your app includes an AR or QR scanner but does not include any additional content or functionality unless the user has access to the AR marker or QR code. While we understand that your app displays additional content when an AR marker or QR code is scanned, to users who do not have access to the AR markers or QR codes, your app only appears to display a camera view.
Next Steps
We encourage you to provide your users with additional content in your app, including directions on how to use your app and information on how to obtain any necessary AR markers or QR codes.
To ensure users have the best experience, apps should provide valuable utility or entertainment, draw people in by offering compelling capabilities or content, or enable people to do something they couldn't do before or in a way they couldn't do it before.
