I have been looking for some time, but without answers, so I ask my question:

I work with firebase and I make a function 'getAllUsers' (which must return all registered user uid) :

function getAllusers(nextPageToken){
    app.auth().listUsers(1000, nextPageToken)
    .then(function(listUsersResult) {
      listUsersResult.users.forEach(function(userRecord) {
        console.log('user', userRecord.toJSON());
      });
      if (listUsersResult.pageToken) {
        // List next batch of users.
        listAllUsers(listUsersResult.pageToken);
      }
    })
    .catch(function(error) {
      console.log('Error listing users:', error);
    });
}

(yes, this is the doc example)

but I get

Uncaught TypeError: app.auth is not a function

I tested :

• auth().listUsers()
• getAuth.listUsers()

I think this is my imports:

import { initializeApp } from "https://www.gstatic.com/firebasejs/9.6.7/firebase-app.js";
import { getAuth, signInWithPopup, createUserWithEmailAndPassword, signInWithEmailAndPassword, GoogleAuthProvider, signOut, getAdditionalUserInfo, reauthenticateWithCredential } from "https://www.gstatic.com/firebasejs/9.6.7/firebase-auth.js";
import { getDatabase, set, ref, update, child, onValue, get } from "https://www.gstatic.com/firebasejs/9.6.7/firebase-database.js";
import { getStorage, ref as sRef, uploadBytes, getDownloadURL, deleteObject } from "https://www.gstatic.com/firebasejs/9.6.7/firebase-storage.js";
const firebaseConfig = {
    apiKey: "XX",
    authDomain: "XX",
    databaseURL: "XX",
    projectId: "XX",
    storageBucket: "XX",
    messagingSenderId: "XX",
    appId: "XX",
    measurementId: "XX"
};

const app = initializeApp(firebaseConfig);
const database = getDatabase(app);
const auth = getAuth(app);
const storage = getStorage(app);

I am currently researching how to use 'admin' for this

Hoping someone can help me, I keep looking, thanks in advance
