I'm trying to use firebase.database.ref() as mentioned in the docs.

firebase.initializeApp(firebaseConfig);
firebase.firestore().settings( { timestampsInSnapshots: true })
// firebase.analytics();

const storage = firebase.storage();
const store = firebase.firestore();
const authenticate = firebase.auth();
    
var matchref = firebase.database().ref("users");

and it's returning this error

firebase_app__WEBPACK_IMPORTED_MODULE_8__.default.database is not a function

I'm using version 8 so this shouldn't be happening.
