Yeah, the new code is doing that now, the function is still just named autoAdvance, you could rename it. If you want to edit the position or styling of the indicator, edit this part in the above code:
function answerFunc() {
// Add indicator element into a fixed position
const indicator = document.createElement("div");
indicator.style.position = "fixed";
// Positioned at bottom right corner
indicator.style.bottom = "0";
indicator.style.right = "0";
// Size
indicator.style.padding = "10px";
// Black with 50% opacity
indicator.style.background = "rgba(0,0,0,0.5)";
// Large border to make the element circular
indicator.style.borderRadius = "99px";
document.body.appendChild(indicator);
}
