React-Slick does not work on SSR projects

I am trying to install react-slick on a NextJS project with [this example](https://codesandbox.io/s/react-slick-playground-8d6h5) but none of the images are showing up.

[As seen here](https://drive.google.com/file/d/1inXscYdXx5Hur6-jA7fSjNnqI5rALqIg/view?usp=sharing), the blue rectangle on the left is the slick `Slider` component which does not display any image at all.
