Launch Google Play Games App using WEBINTENT plugin

I want to open Google play games app on my mobile from my android phonegap build application using WEBINTENT plugin.

window.plugins.webintent.startActivity({
  action: window.plugins.webintent.ACTION_VIEW,
  url: 'facebook://'
},
function() {alert('success')}, 
function(errorMsg) {alert('Failed to startActivity errorMsg=' + errorMsg)}
);

},false);

This code works well to open facebook. How to use it to open play games application.? Thanks.
