Cannot use Gordita font family in Geocortex web

Hi,

I have met a issue while inject CSS to Geocortex web. The font style I am trying to use is: Gordita.

But even if I use !important along with my inject css code(workflow) + include font style cdn url. The font Gordita is still not working in Geocrtex web.

body {

font-family: 'Gordita', sans-serif !important;

}

Always sans-serif. Gordita never works

What is the proper way to add a new font family to Geocortex web?
