Juliusz,
Thank you very much.
It appears in the inputs - Linux/Pulseaudio. I suppose that the new tab participant will be effective though it must be muted to prevent feedback. I will try later and OBS also - very good. I did not know that sharing the tab would include its audio. This is not a web audio though but rather is another program on the computer.
Best regards,
Charles
