Connecting to an Azure Data Lake Gen 2 at a Power BI Workspace throws Access Denied Error

Issue Description:

A new feature has been released for Dataflows which allows us to assign different Azure Data Lake Storage accounts to different workspaces (at the workspace level settings)without using the Power BI tenant level settings. However, while trying to assign a Data Lake Storage to a workspace I got an access denied error message, in an in-house repro.

Error details:

Access Denied. Please try again later or contact support.
