Webook - Ticket comment without any signatures

I have set up a webhook that gets triggered whenever an agent adds a public comment to a ticket.

{{ticket.latest_public_comment}} has the public comment along with the signature. Is there a way to get the public comment without any signatures?

I can retrieve the agent's signature using either {{current_user.signature}} or {{ticket.assignee.signature}}.

I would appreciate if someone could help me extracting this information from the webhook.
