How to re-write this batch.delete function to work for realtime database?

I have a google cloud function, which currently works for firestore. I was able to convert the first variable into real-time database, but don't quite have the knowledge () to do the same for the rest of it.

How do I perform this action in realtime database?

  exports.cleanupUser = functions.auth.user().onDelete(async (user) => {     const dbRef = admin.database().ref('stripe_customers');//admin.firestore().collection('stripe_customers');     const customer = (await dbRef.doc(user.uid).get()).data();     await stripe.customers.del(customer.customer_id);     // Delete the customers payments & payment methods in firestore.     const batch = admin.firestore().batch();     const paymetsMethodsSnapshot = await dbRef       .doc(user.uid)       .collection('payment_methods')       .get();     paymetsMethodsSnapshot.forEach((snap) => batch.delete(snap.ref));     const paymentsSnapshot = await dbRef       .doc(user.uid)       .collection('payments')       .get();     paymentsSnapshot.forEach((snap) => batch.delete(snap.ref));        await batch.commit();        await dbRef.doc(user.uid).delete();     return;   });
