You did fine! Also I enjoy watching other people code and silence, so it was pretty cool.
Another suggestion would be to setup OBS Studio to have different scenes for a bunch of windows (VSC, Chrome, Postman, for example) and have the Automatic Scene Switcher (under Tools) handle them (it basically switch to the active window without you needing to do anything). That way you wouldn’t have to worry about what the viewers are seeing.
Only issue with that is that OBS Studio has an issue with hardware acceleration, so you would need to disable it for Chrome and VSC (otherwise it would just show a black screen).
That’s just a matter of preference, of course!
