Ionic backgorund mode crash - ionic-framework

Question

I am trying to make run a background mode with Ionic, but when I am playing a song, and I enabled the Backgound Mode, the app crashes.
Actually, is posible make the background mode with Ionic?
This is my code:
import { Component } from '#angular/core';
import {NavController} from '#ionic/angular';
import {NativeAudio} from '#ionic-native/native-audio/ngx';
import {BackgroundMode} from '#ionic-native/background-mode/ngx';
#Component({
selector: 'app-home',
templateUrl: 'home.page.html',
styleUrls: ['home.page.scss'],
})
export class HomePage {
constructor(public navCtrl: NavController,
public nativeAudio: NativeAudio ,
public backgroundMode: BackgroundMode) {
this.nativeAudio.preloadSimple('audio1', 'assets/audio1.mp3').then((msg) => {
console.log('message: ' + msg);
}, (error) => {
console.log('error: ' + error);
});
}
public playAudio(){
this.backgroundMode.enable();
this.backgroundMode.on('activate').subscribe(() => {
this.nativeAudio.play('audio1');
});
this.nativeAudio.play('audio1', () => console.log('audio1 is done playing'));
}
}
This is my current config.

I can make it.
The problem is a permission. The FOREGROUND_SERVICE.
I add to platforms/android/app/src/main/AndroidManifest.xml and work
<uses-permission android:name="android.permission.FOREGROUND_SERVICE" />
I hope that it help you
