I’m working on a Google Chrome extension, and I have the HTML of the popup. I have an element called #switch, but document.querySelector(‘#switch’) isn’t working as a selector. It just returns null.

Any ideas on what to do?

document.addEventListener('DOMContentLoaded', function() {
  let switchElement = document.querySelector('#switch')
  console.log(switchElement)
  switchElement.addEventListener('change', () => {
    console.log(switchElement)
  })
})

I tried adding an event listener for DOM CONTENT LOADED, but that didn’t work.
