How to add context menu on a new message window?

I’d like to get a selected text on a new message.

I could same on a viewer of receiving mails.

messenger.menus.create({  
id: “get\_selection\_text”,  
title: “get\_selection\_text”  
contexts: [“selection”],  
onclick: function\_treating\_text  
});
