Fontawesome Icon not Rendering

I'm trying to use fas fa-solid fa-baseball, but it's not rendering. Are there only certain icons that Flarum can render?

bman Try fas fa-baseball

If that doesn't work, you may need to install Blomstra Font Awesome 6

I did. That didn’t work either. I’ll try your suggestion. Thanks!

Do make sure to use the right one, fas no longer exists in v6, it's fa-solid fa-baseball, but only for v6.
