Additional Information

If you attempted to call the Cloud Storage Service Public API from a frontend application you will see an error similar to the following in your Browsers console logs.

Access to fetch at '' from origin '' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.
