Ionic Deploy manually

Hello everybody.
I’m using

import { Deploy } from ‘cordova-plugin-ionic/dist/ngx’;

to deploy live update to my app.
Everything works fine, but I would like to show a progress indicator while the app is updating.
I’m using the following function:

async UpdateApp() {
    this.loading.presentLoading('Updating to last version');
    const update = await this.deploy.checkForUpdate();
    if (update.available) {
      await this.deploy.downloadUpdate((progress) => {
      await this.deploy.extractUpdate((progress) => {
      await this.deploy.reloadApp();

but it looks like the downloadUpdate and extractUpdate doesn’t give usefull information for creating a user-readable progress indicator.
Am I missing something?
