Receive last public comment id in freshdesk webhook automation

So I’m trying to build an automation that will send me back the reply ( conversation ) id when a new reply has been added to a ticket 

The problem is I only have access to `{{ ticket.latest_public_comment }}` which is not really enough and I did read https://support.freshdesk.com/en/support/solutions/articles/87018 but I don’t get what’s different between an email notification and an on reply created webhook both should have access to the reply that triggered said event ?

I have tried `{{comment.id}}` already and it doesn’t seem to work.
