If you want to load bundles outside of the WWW code base it's hard to figure out what the bundle ID's are so we created a bundle loader for this.
What you need to do is include this JS file in your code:
NOTE: the file will be cached so preferably you want to add a custom version to the end of the include e.g.: ?v=${DATE_TIME}
After you have added this to your code this will expose a function to the window scope: window.loadBundle() you can use it then as following:
NOTE: when you add the bundleName make sure to not add any extension, just the folder name will do.
