   Comma separated for multiple fields, or to search all pass a blank value like so: " "
.PARAMETER ActiveSessionID
   Unique ID that maps to the target ActiveSession
   Supply the ActiveSessionID to skip any querying to find the target ActiveSession
.EXAMPLE
   $GetActiveSessionActivitiesJSON = Get-VPASActiveSessionActivities -SearchQuery {SEARCHQUERY VALUE}
.EXAMPLE
   $GetActiveSessionActivitiesJSON = Get-VPASActiveSessionActivities -ActiveSessionID {ACTIVE SESSION ID VALUE}
