How to extend Internet Explorer's share picker on Windows Phone 8?

Question

I am stuck now trying to figure out how to enable easy sharing of links from IE to my app. I am trying to figure out how to extend the share picker for Internet Explorer.
For example, when running IE on WP8, you can bring up the menu at the bottom and click 'share page'. Inside this menu I would like to add my app as an option. Upon selection I would like for it to send the current page's URL to my app.

I found this but the example only extends the photo app's share picker.

Answer 1

It is not possible to extend the share options in IE mobile in this way.
