NIT: should this be called a prefix considering that the /bedrock part is at the end of the URL? I can see that it is the prefix of the path but not really the prefix of the Gateway URL, instead it's rather a postfix in the scope of the URL. Maybe we can rephrase this to "Using the Nexus Gateway URL with the '/bedrock' path".
