Get document data from Firebase Firestore in Node JS

Question

after not finding anything online, I decided to write here. I need to get all the document in the /user/uid collection in Node JS. When I use the Firebase code it replies like this:

Promise {<pending>}

Please help me!

PS: I don't want to use Firebase Admin SDK and await.

"Full" code

var express = require('express');

const { initializeApp } = require("firebase/app");
const { getDatabase, ref, get, child, set, onValue} = require("firebase/database");
const { getFirestore, collection, getDoc, doc} = require("firebase/firestore");

const firebaseApp = initializeApp(firebaseConfig);

// Get a reference to the database service

var app = express();

const PORT = process.env.PORT || 5050

app.get('/', (req, res) => {
    res.send('This is my demo project')
});

const db = getDatabase();
const firestore = getFirestore();


const document = getDoc(doc(collection(firestore, 'users'), "BW5kylV6rtZXtYibpKGc2m1asRm1"));
  
console.log(document);

//Response: "Promise {<pending>}""
