How to create these background and div interactions?

Hi, so I came across this website in the Made in Webflow section:

It’s a really nice website with some great animations and interactions. How might I be able to replicate the mouse interaction with the square background where the squares light up around the mouse?

I’m also wondering if there’s a tutorial on how to create glow hover interactions that some of the boxes have. The glow and stroke follows the mouse when hovering inside the box.

Much appreciated!
