Powerpoint wont use google font

Google font does not work on my PowerPoint, after exporting it into my Mac it appears with symbols and not the whole font family. If I manually search for the font it appears, but only one weight. For now, I have only used Public Sans.
Does anyone know how to fix this? How can I get all the font styles into PowerPoint? Right now it shows up like this:

What does this have to do with Glyphs (an app used to make your own fonts from scratch)?
