And I heard Figma is a heavy adopter of WebAssembly which could be faster when running not in a wrapper like Electron. Since it is WebAssembly one can imagine the so-called “desktop version” has to be also WebAssembly and it has to have a wrapper around it.
If all these are true, OP just need to find a way to load the fonts into the web version.
The pictures OP posted suggest the distro is Mint. At the last time I installed it, I remember double clicking a exe file brings up a dialogue which asks if I want to run it through WINE.
