Brine: Set Slideshow to autoplay and stop on click

Hi there, I'm looking for a solution to make the slideshows autoplay stop when clicked (both the index slideshow and gallery block slideshow)

Here are the temp urls:Index https://horse-blue-mllf.squarespace.com

Gallery block slideshow example : https://horse-blue-mllf.squarespace.com/artworks/landscapes

You need the password wyunabayartist to view.

Thanks in advance
