Retrieving Paginated Power Query data sources via API

Hello,

I'm retrieving data source metadata for Paginated reports across my organization using a combination of the Scanner API report/datasources

This works as expected, except when the report developer used Power Query to "get data". In those cases, the report/datasources API returns no results.

What is the best way to retrieve data source information via API for Paginated reports that use Power Query?

Thanks in advance
