PushNotifications not implemented on android error

I’m testing Capacitor on a very simple vue.js project. LocalNotifications work fine but when I tried PushNotifications from @capacitor/push-notifications then on Android in logcat I see:

Uncaught (in promise) Error: “PushNotifications” plugin is not implemented on android

While having code that starts like this:

PushNotifications.requestPermissions().then(result => {
            if (result.receive === 'granted') {
              PushNotifications.register();
            }
          });

I’ve went through https://firebase.google.com/docs/cloud-messaging/android/client to add google-services.json file as well as edited gradle files. I didn’t define a custom icon. npx cap sync android does passes as well as building/launching the app in Android Studio on a real or emulated device. What could be the source of this?

    "@capacitor/android": "^3.1.2",
    "@capacitor/cli": "^3.1.2",
    "@capacitor/core": "^3.1.2",
    "@capacitor/ios": "^3.1.2",
    "@capacitor/local-notifications": "^1.0.3",
    "core-js": "^3.6.5",
    "vue": "^3.0.0"

Ok, found it :wink: @capacitor/push-notifications was not added to package.json… but now there seems to be some problems with installing the dependencies… edit: version number was wrong.
