Webhook Subscription GraphQL

Greetings I have created a subscription to the RETURNS_REQUEST topic using Postman. I am able to list the subscription to confirm it was successfully created, however I cannot see if the webhook is actually being triggered when I perform a return in Shopify. I stood up a webhook listener via Celigo, but I need to validate from Shopify that the webhook is actually triggered. In my research it seems there should under Settings → Notifications → Event subscriptions an ability to see recently triggered outpoint webhooks, but I am not able to find this in my Shopify dev environment.

You should be able to go to Insights in your app within the Shopify Partners dashboard and see webhook deliveries.

thank you, appreciate the guidance
