Add JS API to Onenote desktop client
most people that I've observed in various large companies use the desktop client, not the web version of the client.
Based on the current docs here(https://docs.microsoft.com/en-gb/office/dev/add-ins/overview/office-add-in-availability#onenote), only the OneNote Office Online version supports the JS API.
It would be useful to provide a seamless experience for both developers and users by making the same framework and add-in available across various clients.
thanks for reading! :)
