title: How to add the "contextual menu command" in Excel addin
body: <p>The <a href="https://github.com/OfficeDev/Office-Add-in-UX-Design-Patterns/blob/master/Helpful%20Templates/AddIn_Template_Excel_Desktop_reference.pdf" rel="nofollow">link</a> shows the "contextual menu command" example. I've searched it for but couldn't find any. It would be great to know its sample code. Also, a list of platforms support this. Thanks.</p>
