On wayland (KDE Plasma) it’s not as seamless. For me it creates two sinks, one of which is voice channel and other is the stream audio stream. It wires my mic to both automatically and i have to manually wire the app audio to stream audio sink. So it does work with extra steps. I use qpwgraph for wiring.
And Vencord has a desktop client “Vesktop” which works like Webcord, with audio in stream too. No presence detection but notifications have worked for me
