Use initializeApp for multiple Firebase databases.

1. Initialize First Database

const primaryApp = firebase.initializeApp(primaryConfig);
const primaryDatabase = firebase.database(primaryApp);

2: Initialize Second Database with databaseId

const secondaryConfig = { ...primaryConfig, databaseId: "your-database-id" };
const secondaryApp = firebase.initializeApp(secondaryConfig, "secondary");
const secondaryDatabase = firebase.database(secondaryApp);
