Current Behavior

I'm using Push notification from capacitor core in a ionic 5 test app but it don't return the push notification received in background to "notification received" function, i've tried the "notification received action performed" but it dont return the title and the body, and thats what i need. I'm saving it to native storage cause i want to show all the notifications received later.

Expected Behavior

I want to build a notification center page with the notifications received when app is open and closed (or is in background).

Sample Code or Sample Application Repo

home.page.html

<ion-header>
  <ion-toolbar>
    <ion-title>
      Ionic Blank
    </ion-title>
  </ion-toolbar>
</ion-header>

<ion-content padding>
<ion-list>
  <ion-item *ngFor="let notif of notifications">
    {{notif}} 
  </ion-item>
</ion-list>
</ion-content>

home.page.ts

import { Component } from '@angular/core';
import { Plugins, PushNotification, PushNotificationActionPerformed, PushNotificationToken } from '@capacitor/core';
const { PushNotifications } = Plugins;
import { NativeStorage } from '@ionic-native/native-storage/ngx';

@Component({
  selector: 'app-home',
  templateUrl: 'home.page.html',
  styleUrls: ['home.page.scss'],
})
export class HomePage {
constructor( private nat:NativeStorage) 
  notifications: any = [];

  ngOnInit() {
    PushNotifications.register();
    PushNotifications.addListener('pushNotificationReceived', (notification: PushNotification) => {
      this.nat.setItem('not', {property: notification.title})
       this.nat.getItem('not').then(
          data => this.notifications.push([JSON.stringify(data.property).replace(this.var, '')].toString().replace(',', ': ')),
          );   
    });
  }
}

Other Information

Data notifications fire pushNotificationReceived if the app is in background, but not if fully closed, it’s a known issue https://github.com/ionic-team/capacitor/issues/2401

Notification notifications don’t fire pushNotificationReceived, only the actionPerformed when you tap them, it’s how notification notifications work, they are handled by the OS, not by capacitor.
