Please consider adding the MSAL library to the ArcGIS Online Notebooks Libraries. MSAL is the Microsoft Authentication Library:
https://pypi.org/project/msal/
https://anaconda.org/microsoft/msal
It allows users and apps to sign in to the Microsoft Identity Platform and obtain API tokens to call the Microsoft Graph API, for example. I use it often for accessing data stored in SharePoint, but it requires a
%conda install msal
line in the AGOL Notebook, and this install ends up being the majority of the runtime of my notebooks that use it. For notebooks that run often, this is a very inefficient use of CPU time. I think having MSAL pre-installed would be very helpful to anyone that wants to access information from Microsoft APIs.
