Hi team, I'm encountering a blocking issue when trying to save changes to my Agent tools. The dashboard returns a generic "Network Error", but the browser console reveals the root cause:

The issue: A CORS policy is strictly blocking the PATCH method on the update-retell-llm endpoint.

Access to XMLHttpRequest at '...' has been blocked by CORS policy: Method PATCH is not allowed

Impact: I cannot update or save any configuration. Steps taken: Tested in Incognito, cleared cache, no VPN/Firewall. The issue is server-side.
