Ligatures and glyphs

Hello !
I’ve been using the font Adobe Garamond lately which provides really beautiful ornaments and ligatures, but I can’t seem to activate them in any other than CSS style, using this code

h1{
  font-feature-settings: "swsh" on;
}

However, since I’d like to use multiple fonts in one text widget, I can’t use only one text style like H1, I would need to be able to turn on those ligatures in another way. Does someone know to get them ? I’ve already tried turning on the ligatures option.
