tengo una base de datos de firebase donde quiero leer parent=>child y parent==>child==>child como se muestra en la captura de pantalla adjunta

Código que lee parent==>child (finance,userid,email...) con éxito

 try { const dbref = ref(db); get(child(dbref,"finance")).then((snapshot)=> { var client=[]; snapshot.forEach(childSnapshot => { const data = childSnapshot.val(); client.push(data); }); AddAllItemsToTable(client); });

¿Cómo puedo leer finanzas==>userid==>id==>value1,value2

 "finance": { "lvAN928K9qXJ5RGiRBUrb6seByM2": { "-N6XXgy0COp30w52pxzZ": { "link": "https://firebasestorage.googleapis.com/v0/b/myhouse-4ba96.appspot.com/o/Documentdocument%3A76094?alt=media&token=5fc3eda7-00ed-4a47-a6e0-1f89dfdabca9" }, "-N6XXh2rkW0jT7MNpO2-": { "link": "https://firebasestorage.googleapis.com/v0/b/myhouse-4ba96.appspot.com/o/Documentdocument%3A76093?alt=media&token=7e2e59ea-7821-4a8b-8b93-9fe17b4b1118" }, "email": "app@email.com", "houseContractor": "General construction ", "houseCost": "2400000", "income": "1200000", "institution": "Commercial Banks", "nic": "123456789", "permit": "Yes" } }

Yo he tratado

 try { const dbref = ref(db); get(child(dbref,"finance")).then((snapshot)=> { var client=[]; snapshot.forEach(childSnapshot =>{ let item1=childSnapshot.val(); client.push(item1); childSnapshot.forEach((grandchildSnapshot) =>{ let item=grandchildSnapshot.val() item.key=grandchildSnapshot.key client.push(item) }); }); AddAllItemsToTable(client); });
