cloud firestore - Query with Data type fields

Question

In the android application that I’m trying to mount, I have a filter screen by registration date and I need to perform the query in the firestore cloud using this field, in the database it is the type Timestamp. I am currently trying to perform the query as follows:

    db.collection("Presenca")
                .whereGreaterThan("datacadastro", datacadastro)
                .get()
                .addOnCompleteListener(new OnCompleteListener<QuerySnapshot>() {
                    @Override
                    public void onComplete(@NonNull Task<QuerySnapshot> task) {
                        if (task.isSuccessful()) {

                            for (QueryDocumentSnapshot document : task.getResult()) {

                                alunosList.add(
                                        new Presenca(
                                                document.getString("nome").toUpperCase(),
                                                document.getString("sala"),
                                                document.getDate("datacadastro")));


                                recyclerView.setAdapter(adapter);
                            }
                        }
                        else {
                            Log.w(TAG, "Error getting documents.", task.getException());
                        }
                    }
                });


    }

Any tips on how to query these fields in the firestore cloud?
