Using Creo View Express as a browser plugin

Where can I find any documentation of how to configure and use the Creo View Express as a plugin in a webbrowser like Firefox.

So far I'm doing a

<embed height="100%" width="100%" name="plugin" src="nvidia-demo.pvz" type="application/x-pvlite9-ed">

It is displayed correctly but I want to disable the toolbar, for example.

Furthermore I need access to the JavaScript API to be able to communicate with the plugin.

I'm using Creo View Express, Version Creo 2.0, Datecode F000 build 23.

Thanks a lot for your help.
