How to get international fonts to work?

I have a site for a client that has mixed English and Thai. Also, we use Weglot for Thai and Chinese. I added a Thai font to go along with our English font via Adobe Fonts… nothing happens. It’s been 12 hours. The set is selected. How do I specify the international font usage mixed on the site? It’s still using the “default” Thai font. You’d think Webflow would be smart enough to recognize adding a “th” font. No? How is it done. Thanks!
