Where to call navigator.registerProtocolHandler?

How and where do I use navigator.registerProtocolHandler to make it work?

.

In this section, you can call the following function to add a custom protocol handler:

navigator.registerProtocolHandler('web+custom', 'http://example.com/rph?q=%s', 'My App');

When I call it from the console, I get

Uncaught DOMException: Failed to execute 'registerProtocolHandler' on 'Navigator': 
Can only register custom handler in the document origin.

This also happens if I include it in the contents of the script, as suggested here

install_protocol.html

<head>
  <title>Web Protocol Handler Sample - Register</title>
  <script type="text/javascript">
    navigator.registerProtocolHandler("burger",
                              "http://www.google.co.uk/?uri=%s",
                              "Burger handler");
  </script>
</head>

I also tried calling it in my background.js script, where it did not throw an error, however the protocol does not seem to respond.

.

Could you please explain how to go through the process of registering and using a custom protocol in Chrome?
