I am following the Debugging page of the official doc as below URL. On the "Inspecting Component Instances" it says "Make sure that the dropdown in the top left corner of the Chrome console says debuggerWorker.js. This step is essential." But I can't find debuggerWorker.js on my dev tools.

What steps should I take to install debuggerWorker.js?
