I have 2 DB in the same project, and I need to trigger “onDocumentCreated” for a specific DB.

The problem is that this function has only 2 parameters :

1. document — The Firestore document path to trigger on.
2. handler — Event handler which is run every time a Firestore create occurs.

So I can not specify the DB instance for the document path.

Here is how I initialize my app :

const app = initializeApp(firebaseConfig);
const auth = getAuth(app);
const db = getFirestore(app);
const dbApplication = getFirestore(app, "application");
const dbUser = getFirestore(app, "user");
