urllib HTTP Error 400: Bad Request | Download OneDrive files from Organisation

Goal: download files within a specified folder from my Organisation's OneDrive using Python.

Following this Towards Data Science tutorial, I provide a OneDrive url, and it generates an API url.

Error:

HTTP Error 400: Bad Request

I suspect this fails because I need to pass permissions in this call from Python's end.

I have tried all combinations of Copy link permissions on OneDrive, both for entire folder and individual file access.
