Excel python anaconda - why is Microsoft's powerbiclient package not included?

Question

Trying the Excel Addin "Anaconda Code" for python. https://support.microsoft.com/en-au/office/open-source-libraries-and-python-in-excel-c817c897-41db-40a1-b9f3-d5ffe6d1bf3e

The Addin installed OK. But the first code I wanted to try uses Microsoft's powerbiclient library (e.g. to connect to a Power BI Report and retrieve data).

But the first lines of python code needed:

from powerbiclient.authentication import DeviceCodeLoginAuthentication

... throw errors indicating this scenario is not supported?

Can the left hand please talk to the right hand and sort this out.
