This section of the docs https://www.npmjs.com/package/@google-cloud/debug-agent#experimental-features (for nodejs) shows that it's available, but when looking in the Cloud Console UI, there is nothing about the inspector feature. How does one use this feature, maybe via kubectl proxy interface or like a cluster ip and the inspector port?
As you can read from the documentation: "The Stackdriver Debugger includes experimental support for the new V8 Inspector Protocol"
So there is not a inspector UI. It just enables a diferent protocol to debug.
Here[1] is the official documentation, and here[2] the link to access the Stackdriver Debug web UI.
