Cursor animation

Hi,

I'm looking to have an animated cursor for my website, but I'm new to using css and other coding languages and I can't solve it. I have anaged to replace the arrow for an emoji but I want an animation similar to this. The second link is for code I have found for it but I don't know where to implement it. ¿Does anyone know if it is possible to do something like that in squarespace?
