I'm trying out the new style JavaScript based office add-ins and can't see how I can add the add-in launcher button to the ribbon. I know that Command add-ins which can add tabs etc are not released yet, I'm just talking about a button that will launch my add-in.
It's a TaskPaneApp.
It seems to be possible because (in my version of office 16 at least) I can see that under the Insert tab, Wikipedia add-in has it own button in the Add-In group.
Currently I've just added a Shared Drive as a trusted location and am launching the app from there. As this is an internal app, it's likely to stay there.
Thanks
