Custom OTF Font not loading in Bubble

Whenever I try adding an otf font following the instructions bubble and people have provided online, it never works, even with the correct name. The link I get isn’t an S3 link like the ones in the examples online. Does anyone know how to do this? Don’t send a youtube tutorial or a blog post that repeats what everything else says, 99% chance I’ve seen it.

Is the process not working for all fonts, or just 1 particular font?
