Sentinel Datalake - How to query outside of defender portal?

I've been doing some testing on Sentinel Datalake but I'm running into a major gap. 
How do we query the datalake outside Jupyter notebooks or the defender portal? 

Currently, this is done by connecting to the log analytics workspace. But I don't see any way to query the datalake from another system.

  • Hi securemetrics​ 

    Microsoft Sentinel's Data Lake is a newer component, and the current access approaches are restricted to: Microsoft Defender Portal, Microsoft Sentinel Notebooks and Microsoft Fabric Lakehouse Explorer.  Querying Sentinel Data Lake from outside these environments is not fully supported. The possible ways are:

    Jupyter Notebooks in Sentinel

    Uses Python SDK to access the Fabric Lakehouse

    Defender Portal > Query View

    Allows KQL querying inside the browser

    Microsoft Fabric Integration

    Power BI, Notebooks, Data Flows can be used if Sentinel Workspace is linked to Fabric Workspace

      Fabric integration would be phenomenal. I cannot find any documentation on this, however.
