          * The iOS App Store doesn't support apps with add-ins that provide links to additional payment systems. However, Office Add-ins running on the Windows desktop or for Office Online in the browser, do allow such links. If you want the UI of your add-in to provide a link to an external payment system on platforms other than iOS, you can use the commerceAllowed property to control when that link is displayed.
