Make hints lightbulb button more obvious

Some users don't notice it at all

I offer 8 options:

1. No change:

2. Simply make the icon larger:

// main.scss
.hint-icon {
  position: fixed;
  bottom: 10%;
  right: 10px;
  //width: 48px;
  width: 72px;
  //height: 48px;
  height: 72px;
}

2. Make it animated (same size). It blinks between white/red background once per second:

// Hints.js
//import hintIcon from "./img/hint.png";
import hintIcon from "./img/hint.gif";

3. Make it animated, AND larger:

Then: basically the same as 0,1,2,3 but, in the middle of the screen, and slightly more elevated from the bottom:

// main.scss
.hint-icon {
  position: fixed;
  //bottom: 10px;
  bottom: 10%;
  //right: 10px;
  right: 50%;
  width: 48px;
  height: 48px;
}

Or something else... (beyond my ability)
