I am having issues deploying an Excel Web Add-In. I would like to deploy it for internal use and not go through store. I have tried 2 different methods of deployment as documented on https://dev.office.com/docs/add-ins/publish/publish
The first method I tried is Office 365 admin center preview. With this method, I can only see the Web Add-In on Excel desktop and not Excel Online.
Then I tried, SharePoint catalog. With this method, I can only see the Web Add-In on Excel Online but not on Excel desktop.
How do I get the web add-in to show on both Excel desktop and Excel Online without going through the Office store?
Thanks in advance!
