Embed powerBI dashboard into a website using python code from github sample

[Anonymous]

Hello,

I am getting below error while trying to embed powerBI dashboard into a website. I am following this documentation (https://docs.microsoft.com/en-us/power-bi/developer/embedded/embed-sample-for-your-organization#work...) step by step but not yet successful. I registered the app in Azure and also provided the client secret to config file but the error is asking a client secret. Can anybody help? Thanks!

Error Details:
Error retrieving Access token
AADSTS7000218: The request body must contain the following parameter: 'client_assertion' or 'client_secret'.
