App Review Rejection for Guidelines 2.1

Hi everyone, can someone tell me what kind of documents mentioned below do I need to provide? I submitted everything I could: design documents, our workspace on bitbucket, trello but still got rejected.

Might be worth posting some more context as just from this image it would be too hard to tell fully what is needed 🙂

Thank you for your post. We've begun investigating this issue but we've been unable to locate your app submission to provide further assistance. Can you provide the name and App ID associated with the app? These can be found in App Store Connect in the App Information tab.
