How to use with React Devtools?

I can’t seem to get React Devtools to work in parallel with RNDebugger. I simply want to inspect DOM elements, but Devtools just says Waiting for React to connect.

So in an effort to debug, I tried reverting the RNDebugger script in my package.json:

  "scripts": {
    "postinstall": "rndebugger-open --revert",
    "start": "node node_modules/react-native/local-cli/cli.js start",
    "test": "jest",
    "devtools": "react-devtools"
  },

But this doesn’t seem to stop the Debugger from opening each time. How can I turn RNDebugger off?
