Flatpak: A LOT of errors

[JapaCZECH]

I have recently switched to linux, but I didn't know that the discord screenshare audio wouldn't work. So I did some research and I ended up finding this, but with lot of errors. I'll just paste them here, because I don't know what they mean. I am using Debian.
