Publish file to community with custom fonts

Hi,

Is it possible to publish a file to the community with custom fonts used in that file?
Or I can use system fonts only? Thanks!

I mean, if I publish the file, someone else outside the organization could use the custom fonts as well without any install, or not?

I have no idea but somehow https://www.figma.com/community/file/886999666531731323 works that way. I don’t have the SF Pro Display font locally yet the page with the text version of the icons renders as if I did.
