Issue with how workbook queries the CSV storage files.

[Networking-G]

From any tab in the dashboard, I can see that it can reach the CSV files, but it returns no results.

When I look at the prerequisite section it says:
Whitelisting functions: that allow Sentinel-ATT&CK workbooks to query CSV storage files. The whitelisting functions are automatically provisioned within the Sysmon threat hunting workbook.

What is the whitelisting function? - I'm not sure it has automatically started working for me.
Is there a way to troubleshoot this?
