Is there another way to differentiate JSM Widget created tickets than just request-channel-type=api?

I’m trying to setup a Slack integration in Jira Service Management using JQL. I want to capture any JSM project created support tickets that get created via the portal, email and widget … and post those to a Slack channel. We use Halp (Atlassian Assist) as well, and those tickets already get posted to that channel. It looks like Halp and JSM widget created tickets both have a request-channel-type = api. Since I don’t want the new Halp ticket notification being essentially duplicated, is there another indicator on a ticket object that’d differentiate that it came from the widget (as opposed to Halp)?
