Hi,

I want to create an add-in for Office 365 calendar. I have created an add-in for outlook using Yeoman generator and it works well.
However, this add-in is not visible in Outlook Calendar.

The add-in icon is visible, but my custom add-in has not been added. Refer below image for my custom add-in (Office365_Calendar).

I am new to office add-in development and this is my first project.
However, when i read the generated manifiest file, I feel that it has something to deal with my configurations inside it. Refer below contents inside the manifiest file.

I would be glad, if someone could help me with this and guide me where to start with Office 365 calendar add-ins.
