Recently quizzis updated their API. previously it was possible to get the answers by fetching https://quizizz.com/_api/main/v4/students/game/ and accessing data.questions. but it seems that the "questions" from "data" is not available anymore after the Quizizz patch on May 26.

If you want to test for yourself, here's a simple code to access the API: (execute it on your quizziz room dev console)

function getRoomHash(){
  const rootObject = document.querySelector("body > div")
  if (!rootObject) throw new Error("Could not retrieve root object");
  const vue = rootObject.__vue_app__.config.globalProperties.$store.getState().game

  return vue.data.roomHash;
}

window.location.href = `https://quizizz.com/_api/main/v4/students/game/${getRoomHash()}`

Possibly we wont have any quizziz hack anymore, at least with this method.
