How to use same userData folder in dev mode as in build mode?

[Shinigami92]

My package.json:

{
  // ...
  "productName": "watchlist",
  "scripts": {
    "dev": "quasar dev -m electron",
    "build": "quasar build -m electron",
    // ...
  },
  // ...
}

app.getPath('userData')

dev: ~/.config/Electron/
build: ~/.config/watchlist/ (or to be clear ~/.config/<productName>/)
