error when I try to run:

flatpak run de.shorsh.discord-screenaudio
Gtk-Message: 02:27:47.128: Failed to load module "canberra-gtk-module"
Gtk-Message: 02:27:47.129: Failed to load module "canberra-gtk-module"
qt.qpa.qgnomeplatform: Could not find color scheme  ""
Qt: Session management error: Could not open network socket

I install sudo apt-get install libcanberra-gtk-* , but it doesn't help.

I think the main problem is that I try to do it on Ubuntu 20.04. I tried to build it, but using Qt5 (I think no Qt6 on ubuntu 20.04)

The version of the KDE Frameworks in Ubuntu 20 is too old. You can try to build without them by running the following.

rm -rf build
cmake -B build -DSKIP_KDE=ON
cmake --build build --config Release

But that also means you will not have global shortcuts and better notifications.

doesn't work, too old KDE. So, can't build on 20.04.
