@ravikd744 Thanks for the PR. Can u please add more context to the PR? what's problem the users may face and the where the sample can help. Thanks.

@arvindshmicrosoft @rajmera3 for user samples review.

Hi @shivsood , i couldnt find any reference sample for using MSAL with this connector, particularly the list of jars to be included in the databricks cluster. Hopefully, it helps users to get started with the MSAL integration for the connector with ease.

Thanks @ravikd744! Are you able to make a notebook that has your comment of what the dependency jars are as well as this code? Don't want users to lose that information and then get stuck trying to use this sample.

Ask for notebook or code comment of dependency jars
