Go Live. View my broadcast in another window (second display).

I capture the game and broadcast it to the channel. When I switch from Discord to a game or other application, the preview is paused.

And I would like to expand the viewport and display it on another monitor in order to control what is being streamed there (for example, as in the OBS). To avoid misunderstandings. At least it was a surprise for me that being in the game and pressing Alt + Tab, Discord broadcasts this too. But I have chosen the old Alt + Tab method (which was in Windows 7).
