How to add custom fields with eventlog on winlogbeat

Hi,

I have added custom fields for eventlog security but the custom fields are not showing when it send to the logstash server.

AM sending the data using winlogbeat from windows 10 home edition.

Custom fields are supported in Winlogbeat 5.0. See https://www.elastic.co/guide/en/beats/winlogbeat/master/configuration-winlogbeat-options.html#winlogbeat-configuration-fields
