Firestore - an object with an internal object

Question

The user object that takes the parameter (DocumentSnapShot documentsnapShot). is also an internal object from firebsae that retrieves a snapshot and sets values ​​to my user model, also has its argument (DocumentSnapShot documentsnapShot). However, I want to get the data from firabase and pass it into my own argument, because I have some data, not just firebase. And its impossible to iterate through firestore without overriding.

heres code

public UserSettings getUserSettings(DocumentSnapshot documentSnapshot){
    Log.d(TAG, "getUserSettings: retrieving user account settings from firestore");

    DocumentReference mSettings = mFirebaseFirestore.collection("user_account_settings").document(userID);
    mSettings.get().addOnSuccessListener(new OnSuccessListener<DocumentSnapshot>() {
        @Override
        public void onSuccess(DocumentSnapshot documentSnapshot) {


            UserAccountSettings settings = documentSnapshot.toObject(UserAccountSettings.class);
            settings.setDisplay_name(documentSnapshot.getString("display_name"));
            settings.setUsername(documentSnapshot.getString("username"));
            settings.setWebsite(documentSnapshot.getString("website"));
            settings.setProfile_photo(documentSnapshot.getString("profile_photo"));
            settings.setPosts(documentSnapshot.getLong("posts"));
            settings.setFollowers(documentSnapshot.getLong("followers"));
            settings.setFollowing(documentSnapshot.getLong("following"));

        }
    });
}
