Genesys Webhook to Slack on Queue SLA Breach

Trying to trigger a Slack notification when a queue breaches SLA. The webhook hits my Node server, but the event payload lacks the queueId or slaBreach fields needed for the message.

Here’s the handler:
app.post('/webhook', (req, res) => { console.log(req.body); });

Logs show a generic interaction event. How do I filter for the specific SLA breach event type?
