I just use Discord from my browser where it's at least sandboxed and doesn't have access to my filesystem.

Since it's an electron app anyway it's basically the same as the app.

I honeslty haven't had any issues with it. But I'm sire others are. I feel like that's the biggest challenge since there's a ton of distros and architectures

I use it in the browser on Linux and it works fine. Everything works. They're electron app is poorly deployed.
