Cordova plugin not recognized

I am creating a cordova project, installing nodejs, cordova, etc. I am using CLI methods.

To add a plugin, I use:

cordova plugin add cordova-plugin-dialogs

      

        
        
        
      

    

In my HTML:

document.addEventListener("deviceready", onDeviceReady, false);

function onDeviceReady() {
  navigator.notification.beep(1);
}

      

        
        
        
      

    

In my config.xml file:

  <feature name="Notification">
    <param name="android-package" value="org.apache.cordova.dialogs.Notification" />
  </feature>

      

        
        
        
      

    

I have this in Android Studio console

"Uncaught TypeError: Cannot read property 'beep' of undefined"

      

        
        
        
      

    

I added a media plugin with the same problem, but the vibrating plugin works well.
