remove traffic lights

To remove the traffic lights (minimize, maximize, and close buttons) from the window title bar, you can use the following code in your main process:

const { app, BrowserWindow } = require('electron')

app.whenReady().then(() => {
  const mainWindow = new BrowserWindow({
    titleBarStyle: 'hidden',
    frame: process.platform === 'darwin' ? false : true, // set to false for macOS
    // ... other options
  })
  // ... load your app
})

The titleBarStyle option is set to "hidden" to hide the default title bar and its associated buttons. On macOS, you may also want to set the frame option to false to remove the window frame and enable native macOS window decorations.
