FIREBASE_DATABASE_URL not present

[g-tejas]

Hey,
In the .env.example file there is a database url param, but when I set up my firebase app, that database url param wasnt presented to me and i cant seem to find it, where can i get it?

// For Firebase JS SDK v7.20.0 and later, measurementId is optional
const firebaseConfig = {
apiKey: "",
authDomain: "",
projectId: ,
storageBucket: "",
messagingSenderId: "",
appId: "",
measurementId: ""
};
