How to trigger pushObject.on('notification') when app is closed

Ionic Framework
1

Hi,

I want to trigger pushObject.on(‘notification’) when my app is closed or is not running.

data.additionalData.foreground is work but,
data.additionalData.background and data.additionalData.coldstart is not work

Here is my “app.component.ts” code

import { Push, PushObject, PushOptions } from '@ionic-native/push/ngx';


pushObject.on('notification').subscribe(async (data: any) => {
      console.log('message -> ' + data.message);

      if(data.additionalData.foreground) {      // if its true app is in foreground
        this.router.navigateByUrl('/tabs/haber');
        let alert = await this.alertCtrl.create({
          header: data.title,
          message: data.message,
          buttons: [{
            text: 'İptal',
            role: 'cancel'
          }, {
            text: 'Aç',
            handler: () => {
              //TODO: Your logic here
              this.router.navigateByUrl(data.message);
            }
          }]
        });
        await alert.present();
     }else{                                    // else app is in background 
        console.log('onNotificationbackground');
     
        if (data.additionalData.coldstart){

          this.router.navigateByUrl('/tabs/haber');
          let alerts = await this.alertCtrl.create({
            header: data.title,
            message: data.message + 'coldstart',
            buttons: [{
              text: 'İptal',
              role: 'cancel'
            }, {
              text: 'Aç',
              handler: () => {
                //TODO: Your logic here
                this.router.navigateByUrl('/tabs/menu');
              }
            }]
          });
          await alerts.present();
        }
        else if (data.additionalData.background){
          this.router.navigateByUrl('/tabs/haber');
          let alerts = await this.alertCtrl.create({
            header: data.title,
            message: data.message + 'back',
            buttons: [{
              text: 'İptal',
              role: 'cancel'
            }, {
              text: 'Aç',
              handler: () => {
                //TODO: Your logic here
                this.router.navigateByUrl(data.message);
              }
            }]
          });
          await alerts.present();
        }
       }
      });
