Email auth is working, how to add social auth?

Hi guys, I’ve followed this tutorial https://javebratt.com/angularfire2-email-auth/ to enable email auth on the ionic app.

Now I have the following elements in my app.module.ts

const myFireBaseAuthconfig ={
    provider: AuthProviders.Password ,
    method: AuthMethods.Password
}

and

  imports: [
    IonicModule.forRoot(MyApp),
    AngularFireModule.initializeApp(firebaseConfig,myFireBaseAuthconfig),
    AngularFireModule.
  ],

so now I’d like to add for example Facebook auth. Everything behind the scene like connecting firebase with the Facebook app is done, but my question is about the code.

I know how I could replace the email auth with the Facebook one, by using the following config and making the adequate changes in the auth pages

const myFireBaseFacebookAuthConfig = {
      provider: AuthProviders.Facebook,
      method: AuthMethods.Popup
    }

But how should I edit my app.module.ts to have both ?

Thanks !
EDIT: And happy new year!
