HTML / Webplayer help! Where do I add this line of code on the HTML script for it to disable context menu?

This is my webplayer script Where do I add this code to `config.params["disableContextMenu"] = true;` What I need is to disable context menu from this HTML, since this HTML makes my webplayer game 100% size (fill the whole browser), which cant be done from a regular unity 3d no context build. Any help greatly appreciated, I'm stuck at dis ._.
