Auto List - set Carousel Grid row to match content height

Site URL: https://amritaedtc.squarespace.com/?password=test

I am using the Auto List Carousel section as a testimonial slider, and am trying to apply an "min-content" style auto-height to the grid rows. Because I have one slide that is larger than the rest due to its content (see photos), the smaller slides take on that same minimum height, leaving the arrows at an awkward distance from the content.

I tried to insert the following code to change the grid rows to match the height of the content, but it is not working. Any thoughts?

.user-items-list-carousel__slides {
grid-auto-rows: minmax(min-content, max-content);
}
