Font Awesome and Axure RP 10

I had used font awesome on Axure wireframes a few years ago. The icons no longer appear (square box). I looked up ways to fix it and the icons don’t seem to update. I used font awesome 5, but would also like to update to font awesome 6. I tried the kit, cdns, and font mapping but nothing seems to work. I would also like to use font awesome as text instead of from the library.
