Slick image carousel responsive

Hi team,
First congratulations for the plugin.
My issue is regarding responsive layout of the carousel:
in desktop shows 3 images and when we resize the page to mobile size it shows only one as expected, but the problem is that doesn’t show 2 images for tablet. it shows the 3 as same, and very small, with no readability.
We are trying to achieve whats happening on https://www.hypertrophycoach.com/ about the transformation.
It goes from 4 images on desktop to 2 images on tablet and finally one on mobile.

Please help us. I’ve read all the posts here on plugin page but couldn’t find a solution.

our page where plugin is running is:

Best regards,

Joana.
