Customising product titles of the Related Products section

Site URL: https://www.cowanandsons.squarespace.com

Please help! 🥴 I'm trying to make the product titles smaller in the "Related Products" section. The two most logical options aren't working:

.ProductItem-relatedProducts-link {
  font-size: 16px !important;
}

and

a.ProductItem-relatedProducts-link {
  font-size: 16px !important;
}

I've tried some random things too, but having no success!
