I received the following rejection email from Apple for an ARkit app build with Unreal 4.24:

---
Your app uses the "prefs:root=" non-public URL scheme, which is a private entity. The use of non-public APIs is not permitted on the App Store because it can lead to a poor user experience should these APIs change.

Specifically, your app uses the following non-public URL scheme:

MetalTools.framework

Continuing to use or conceal non-public APIs in future submissions of this app may result in the termination of your Apple Developer account, as well as removal of all associated apps from the App Store.

---

Everything in the app is blueprint based and I am building with Distribution mode so please advice me on how I can disable this!

thank you
