Hello,
Thanks for the responses. To start with, I'm trying to enumerate the notebooks available to me as a business user, so I guess option #3 that @rezecib outlined.
I'm unsure how to do this, and have tried listing shared and linked notebooks, but neither of these correspond to the full list of notebooks available in the business to me using the client or web API, and indeed list only a small fraction of them. I've attached the relevant portions of my current code, which as you can see is based on some of the example code available on the official site/GitHub code.
Very gratef
