How can com.google.android.documentsui be missing in Android 13?

I cannot run my favourite MP3 player on my Redmi 11S and Android 13, because the com.google.android.documentsui is missing. How it is possible? App author claims that is an essential system component that must exist, exists by default in Android 11+ and is only gone when user tries to debloat the phone which I personally didn't do. Is there any other reason for com.google.android.documentsui for not existing? Has Redmi removed it intentionally from their Redmi 11S' version of Android? Can Family Link be blocking or removing this file?
