Capacitor FCM Push notifications

Hi guys, i implemented the push notifications in my ionic-angular project with the FCM Capacitor. I followed the documentation on installing the Capacitor plugin in the project. But in the part where I get the notification with the app open on the iphone it doesn’t the way i want, i just want to pop up a toast and not a normal notification, only on android i can see that toast working not on iphone. From what I saw it is a bug of the Capacitor itself but I didn’t see anyone that I can solve.

Capacitor Link Docs.:

Has anyone gone through the same? If yes, has anyone solved it? I found no solution.

My approach.:

import { Injectable } from "@angular/core";
import { AlertController, ToastController } from '@ionic/angular';
import { FirestoreService } from './firestore.service';
import { Plugins, PushNotification, PushNotificationToken, PushNotificationActionPerformed } from '@capacitor/core';
import { User } from "../_models/user.model";

const { PushNotifications } = Plugins;

@Injectable({ providedIn: 'root' })
export class PushNotificationService {

        private firestoreService: FirestoreService,
        private toastController: ToastController,
        private alertController: AlertController

    initPush(user: User){

        alert('teste de notificações');

// Request permission to use push notifications
// iOS will prompt user and return if they granted permission or not
// Android will just grant without prompting
        PushNotifications.requestPermission().then( result => {
        if (result.granted) {
            // Register with Apple / Google to receive push via APNS/FCM
        } else {
            // Show some error

        // On success, we should be able to receive notifications
        (token: PushNotificationToken) => {
            this.firestoreService.updateDeviceToken(user._id, token.value);
            alert('Push registration success, token: ' + token.value);

        // Some issue with our setup and push will not work
        (error: any) => {
            alert('Foi encontrado erro em: ' + JSON.stringify(error));

         // Show us the notification payload if the app is open on our device
        (notification: PushNotification) => {
            alert('Push received: ' + JSON.stringify(notification));

        // Method called when tapping on a notification
        (notification: PushNotificationActionPerformed) => {
            alert('Push action performed: ' + JSON.stringify(notification));


    async notificationToast() {
        const toast = await this.toastController.create({
          position: 'top',
          color: 'dark',
          message: 'Nova notificação',
          duration: 2000
