Using native Mac fonts on Webflow project

Hey guys,

I’m trying to use a native Mac font - Founders Grotesk - for a Webflow project. I get the font for free because I have a Mac, and I’ve been using it in Figma, but I can’t figure out how to get a ttf, etc file through the Font Book app in order to import it into Webflow.

Any help is appreciated, thanks!
