I want to alert another APP, with Ionic 3 and Cordova 8

Question

Hello!

I want to send an alert from one app to the other, I’m developing both and they already talk, but I could not do this issue of alert.

<ion-item style="align-items: center;">
      <button color="green" ion-button (click)="presentAlert()">
        <ion-icon name="alert"></ion-icon>&nbsp; {{'o que quer alertar?' | translate}}
      </button>
    </ion-item>

presentAlert() {
  let alert = this.alertCtrl.create({
    title: '!!* Atenção *!!',
    subTitle: 'Uma mensagem de alerta!',
    buttons: ['Já vou ver...']
  });
  alert.present();
}

In the app itself, it works normal. How would I send to the other app?
