Do native Squarespace fonts have opentype features that can be modified with css?

I am using Bookmania Regular for the font on my site. I need to be able to customize it so that it has Roman/Italic Forms and the Jensen e, which are SS02 and SS04. 

When I've needed to use OpenType features on Squarespace in the past, I've always had success using this website: (https://clagnut.com/sandbox/css3/) to generate a few lines of CSS. 

What I put in my CSS was:

h1 {
-moz-font-feature-settings:"ss02" 1, "ss04" 1;
-ms-font-feature-settings:"ss02" 1, "ss04" 1;
-o-font-feature-settings:"ss02" 1, "ss04" 1;
-webkit-font-feature-settings:"ss02" 1, "ss04" 1;
font-feature-settings:"ss02" 1, "ss04" 1;
}

This is not working for me, and I'm thinking it has to be because on the clagnut site, it's taking my local version of Bookmania, which is from Adobe. Since Bookmania is available on Squarespace, that's the version that I'm using rather than buying the web license (which is a recurring annual subscription rather than a purchase). Does Squarespace include all of the OpenType features that the fonts they carry have? Or would the code just be different since it's a different version / file than the one that comes from Adobe?
