Eye Element on Logo Following Mouse/Cursor

Hey, hoping anyone could simply explain to me how to do this coding for my website. Not sure how to incorporate information I found from sites like this: www dot codepen at
io/whipcat/pen/ExKPQqZ, but was able to find a link within Velo that kinda helps. I’m not sure if I need to use all HTML, CSS, JS coding in Velo. If anyone has a quick fix or shortcut feel free to let me know.
