IONIC 3 - Open app on notification received - firebase

Question

My app's notification is working fine, receiving notifications on background and foreground, using firebase-native plugin .Now, my client needs the app open when the notification is received without any user iteration.
I've found was this, but has no correct answer for me.
On my debug, I've realize that the notification is received via broadcast by FirebaseInstanceIdReceiver. So, I've tried:
Modify the
plugins/cordova-plugin-firebase-lib/plugin.xml
This compile but nothing happens.
Modify the config.xml and use to replace config.xml of firebase-lib and merge with mine, calling the right intent.
This not compile and give me this error:
MY QUESTION IS: What is the best approach to archive this? Can someone guide me with a real example?
Thank you for your time!

If someone need this, the solution that work for me was use the "#ionic-native/background-mode" plugin.
The resolution for this problem it's pretty easy actually. No need for intent, just install the '#ionic-native/background-mode'.
For Ionic 3, install the plugin using this command:
ionic cordova plugin add cordova-plugin-background-mode
npm install --save #ionic-native/background-mode#4
File: app.module.ts:
import {BackgroundMode} from "#ionic-native/background-mode";
Add on providers:
providers: [
BackgroundMode,
...
],
File: app.component.ts:
Import the background-mode plugin:
import {BackgroundMode} from "#ionic-native/background-mode";
Add on constructor
constructor(
platform: Platform,
statusBar: StatusBar,
splashScreen: SplashScreen,
...
private backgroundMode: BackgroundMode) {
this.backgroundMode.enable();
this.backgroundMode.excludeFromTaskList();
this.backgroundMode.overrideBackButton();
// this.backgroundMode.setDefaults({silent: true});
this.backgroundMode.on('activate').subscribe(value => {
this.backgroundMode.disableWebViewOptimizations();
});
}
File: fcm.ts
Here is where all Firebase notification are. First, import the background-mode:
import {BackgroundMode} from "#ionic-native/background-mode";
Now, we just call these two functions on onNotificationOpen, which is the function that firebase call when notification arrives:
listenToNotifications() {
return this.firebaseNative.onNotificationOpen()
}
this.listenToNotifications().subscribe(
((msg: any) => {
// 'These two functions make the magic'
this.backgroundMode.unlock();
this.backgroundMode.moveToForeground();
if (!msg.tap)
this.events.publish(this.dataInfo.eventFcmNew, msg)
else
this.events.publish('push', 'NotificationsPage')
})
)
That's it!
