How to Enable Right-Click In NightmareJS?

I'm currently testing in NightmareJS using different viewports and agents. I'm automating visits to a site that has a lot of complex scripting and styles. I'm not able to sufficiently duplicate the agent and view in a separate test browser such that the site displays the same content for me as it does when I'm visiting with Nightmare. For this reason, I need to be able to right-click elements in Nightmare's Electron window so that I can inspect specific elements in the DOM.

The problem is that right-click is disabled in the Electron window. I found this answer which describes adding code to the render process:

// Importing this adds a right-click menu with 'Inspect Element' option
const remote = require('remote')
const Menu = remote.require('menu')
const MenuItem = remote.require('menu-item')

let rightClickPosition = null

const menu = new Menu()
const menuItem = new MenuItem({
  label: 'Inspect Element',
  click: () => {
    remote.getCurrentWindow().inspectElement(rightClickPosition.x, rightClickPosition.y)
  }
})
menu.append(menuItem)

window.addEventListener('contextmenu', (e) => {
  e.preventDefault()
  rightClickPosition = {x: e.x, y: e.y}
  menu.popup(remote.getCurrentWindow())
}, false)

Note: this code would probably need to be altered as mentioned in the referenced answer but where would I add such code when working with Nightmare?

The main script isn't the same as the Electron render process script AFAIK. As for that sort of solution, this would probably be a better one but how to invoke?
