Como pegar os dados de um item do RecyclerView ao clicar nele usando Firebase Firestore?

Boa tarde....Estou trabalhando em meu TCC e estou desenvolvendo uma app de controle de pedidos no Android Studio usando Java e Firetore, estou com uma dúvida sobre como pegar os dados de um produto na ao clicar na RecycleView, consigo pegar a posição e ID do produto no Firestore. Classe Adapter:

public class ProductAdapter extends FirestoreRecyclerAdapter<Product, ProductAdapter.ProductHolder> {

 private OnItemClickListener listener;

 public ProductAdapter(@NonNull FirestoreRecyclerOptions<Product> options) {
 super(options);
 }

 @Override
 protected void onBindViewHolder(@NonNull ProductHolder holder, int position, @NonNull Product model) {
 holder.mTextDescription.setText(model.getDescription());
 holder.mTextMeasure.setText(model.getMeasure());
 holder.mTextWeight.setText(String.valueOf(model.getWeight()));
 holder.mTextQuantity.setText(String.valueOf(model.getQuantity()));
 holder.mTextSalePrice.setText(String.valueOf(model.getSalePrice()));
 holder.mTextExpirationDate.setText(model.getExpirationDate());

 }

 @NonNull
 @Override
 public ProductHolder onCreateViewHolder(@NonNull ViewGroup viewGroup, int i) {
 View view = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.row_product_list,
 viewGroup, false);

 return new ProductHolder(view);
 }

 class ProductHolder extends RecyclerView.ViewHolder {

 TextView mTextDescription;
 TextView mTextMeasure;
 TextView mTextWeight;
 TextView mTextQuantity;
 TextView mTextSalePrice;
 TextView mTextExpirationDate;

 public ProductHolder(@NonNull View itemView) {
 super(itemView);
 this.mTextDescription = itemView.findViewById(R.id.textView_product_description);
 this.mTextMeasure = itemView.findViewById(R.id.textView_product_measure);
 this.mTextWeight = itemView.findViewById(R.id.textView_product_weight);
 this.mTextQuantity = itemView.findViewById(R.id.textView_product_quantity);
 this.mTextSalePrice = itemView.findViewById(R.id.textView_product_salePrice);
 this.mTextExpirationDate = itemView.findViewById(R.id.textView_product_expirationDate);

 itemView.setOnClickListener(new View.OnClickListener() {
 @Override
 public void onClick(View v) {

 int position = getAdapterPosition();
 if (position != RecyclerView.NO_POSITION && listener != null) {
 listener.onItemClick(getSnapshots().getSnapshot(position), position);
 }
 }
 });
 }
 }

 public interface OnItemClickListener {
 void onItemClick(DocumentSnapshot documentSnapshot, int position);

 }

 public void setOnItemClickListener(OnItemClickListener listener) {

 this.listener = listener;

 }

}

	E a Activity que lista os itens na RecycleView:

public class ProductListActivity extends AppCompatActivity {

//firestore instance

 private FirebaseFirestore db = ConfigurationFirebase.getFirebaseFirestore();
 private CollectionReference productRef = db.collection("products");

 private static final String TAG = "ProductListActivity";

 private ProductAdapter productAdapter;

 @Override
 protected void onCreate(Bundle savedInstanceState) {
 super.onCreate(savedInstanceState);
 setContentView(R.layout.activity_list_product);

 setUpRecycleView();
 }

 private void setUpRecycleView() {

 Query query = productRef.orderBy("description", Query.Direction.ASCENDING);

 FirestoreRecyclerOptions<Product> optionsProduct = new FirestoreRecyclerOptions.Builder<Product>()
 .setQuery(query, Product.class)
 .build();

 productAdapter = new ProductAdapter(optionsProduct);

 RecyclerView recyclerView = findViewById(R.id.recycler_view_listProducts);
 recyclerView.setHasFixedSize(true);
 recyclerView.setLayoutManager(new LinearLayoutManager(this));
 recyclerView.setAdapter(productAdapter);

 productAdapter.setOnItemClickListener(new ProductAdapter.OnItemClickListener() {
 @Override
 public void onItemClick(DocumentSnapshot documentSnapshot, int position) {
 Product product = documentSnapshot.toObject(Product.class);
 String id = documentSnapshot.getId();
 String path = documentSnapshot.getReference().getPath();

 // DocumentReference docRef = db.collection("products").document(id);
 // docRef.update("description", "Pastel de Queijo");

 Toast.makeText(ProductListActivity.this, "Position: " + position + "ID: " + id, Toast.LENGTH_SHORT).show();

 openProductDetails();

 }
 });

 }

 @Override
 protected void onStart() {
 super.onStart();
 productAdapter.startListening();
 }

 @Override
 protected void onStop() {
 super.onStop();
 productAdapter.stopListening();
 }

 public void openProductDetails() {
 Intent intent = new Intent(ProductListActivity.this, ProductDetailsActivity.class);
 startActivity(intent);
 finish();
 }

}
