Suppress notifications for tickets created in Halp

[Daniel Longfellow]

We have a classic Jira Service Management project set up for an internal helpdesk and have recently introduced a Halp integration.

It's working well but I'd like to get to a point where email notifications for tickets created in Slack via Halp are suppressed in Jira as communications happens via Slack already.

I have a custom field setup in Halp that I can use as a filter but don't know how in Jira to go about suppressing all notifications based on this field.

Anyone have any pointers?
