Using CSS @font-face in HTML iFrame.

I am building a portion of my website using the HTML iFrame offered by editorX. To use your own font one must first find the source of the font file hosted on your website, similar to how you would find a link to a video uploaded on your site. I was wondering if anyone knows where I can access the font link on EditorX. Below is an example of @font-face in CSS.

@font-face { font-family:"Hanley W05 Sans Wide Extra"; src:url("Fonts/6350530/1c15d52d-332b-4300-84af-55c4b29a1092.woff2") format("woff2"),url("Fonts/6350530/9236ec9e-63c8-4702-8a6a-245751fc21b6.woff") format("woff"); }
