Querying read-only admin api for activity

Hi,

I'm looking at creating service principal to use to log in to Power BI admin so that the GetActivityLog can be queried from Python - unattended.  We'll be running Python to ETL data to our lake.   Our normal admin accounts in Power BI have MFA.

https://docs.microsoft.com/en-us/power-bi/admin/read-only-apis-service-principal-authentication

If I follow steps from page aboveI guess that should get me what I need.   Is there any documentation for connecting with service principal from the client (python) - I guess I need to hit an auth site for token and then use that with request to the API.  

Best
