function[Aggregate]falsecount(as=_count)Specifies which aggregate functions to perform on each session. Default is to count(as=_count) the elements in each group.
maxpausestringfalse15mDefines the maximum pause between sessions i.e., events more than this far apart will become separate sessions. Defaults to 15m.
