Definitions for Power BI events

Anonymous 

This is only mildly helpful.  There is a list within this article.. but it is not complete and each item is not fully described.  I am specifically looking for the definition for "GetSnapshots"... I have no idea how or what this is.. Users are coming up as performing this activity and I am not sure what it is.. or how to even do this myself..

There has to be a Document somewhere that describes all the Audit Events being tracked and available to be reported on?  I can't imagine that MS would not have sucha document....
