Node + ExpressJS debugging on VS Code is not watching for changes

I have a Node + ExpressJS backend test server which I run (and watch for changes) with the following command:

$ npm run dev

That’s because I have the following: package.json:

{
  ...
  "main": "index.js",
  "type": "module",
  "scripts": {
    ...
    "dev": "cross-env DEBUG=app nodemon --exec babel-node src/index.js"
  },
  ...
}

I also can debug the backend code with VS Code by using this: /.vscode/launch.json:

{
  // Use IntelliSense to learn about possible attributes.
  // Hover to view descriptions of existing attributes.
  // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
  "version": "0.2.0",
  "configurations": [
    {
      "name": "Backend Debug",
      "type": "node",
      "request": "launch",
      "program": "${workspaceFolder}/backend/src/index.js",
      "runtimeExecutable": "${workspaceFolder}/backend/node_modules/.bin/babel-node",
      "runtimeArgs": ["--nolazy"]
    }
  ]
}

My problem is: Even though I can properly debug the backend code with the launch.json above, the process is not watching for changes. I mean, if I do a change on the code then the server doesn’t restart with new changes.

Any idea on how to do this?

Thanks!
