Сan't get data from Firestore, no errors

I'm trying to get data from the Firestore. The code below, mostly taken from the docs doesn't get anything from the database, although writing data works without issue.

Code from fragment:

override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
    super.onViewCreated(view, savedInstanceState)
    init()
}

private fun init() {
    db = FirebaseFirestore.getInstance()
    mFirestoreRef = db.collection("users").document(USER_ID).collection("deals")
    val viewModel = ViewModelProvider(this).get(DealsViewModel::class.java)
    viewModel.retriveData(mFirestoreRef)
    recyclerView = binding.rcView
    adapter = TradeNoteAdapter()
    recyclerView.adapter = adapter
    var notes = viewModel.getAllNotes()
    adapter.setList(notes)
}

Code from ViewModel:

import android.widget.Toast
import androidx.lifecycle.ViewModel
import com.google.firebase.firestore.CollectionReference
import space.timur.tradenotefirebase.APP
import space.timur.tradenotefirebase.model.TradeNoteModel

class DealsViewModel : ViewModel() {

private var notes: ArrayList<TradeNoteModel> = ArrayList()

fun retriveData(firestoreReference: CollectionReference){
    firestoreReference.get()
        .addOnSuccessListener { documents ->
            for(document in documents){
                var note = document.toObject(TradeNoteModel::class.java)
                notes.add(note)
            }
        }.addOnFailureListener{ e->
            Toast.makeText(APP, e.message, Toast.LENGTH_SHORT).show()
        }
}

fun getAllNotes(): ArrayList<TradeNoteModel> {
    return notes
}

}
