I want to export my logs to GCP via the Webhook Integration in the dashboard. I set up a cloud run service and want to use the "HMAC secret" which convex offers to check the signature. The problem is that when I generate the secret, convex automatically sends a test message, before I can copy over the HMAC, and I get a 403. After this convex doesn't try to export any more logs. How can I retrigger the webhook? I have tried to change the URL and then change it back, but this doesn't retrigger sending.
