hey, this looks great! a few nitpicks:

• can you remove the console logs in _getRawDesktopSources? this feels a bit "noisy"
• will this not work on linux? any reason for this check if (process.platform === "darwin" || process.platform === "win32")

thanks!

Thanks for reviewing this pull request.
I removed the console log from the successful try case, do you think the console log in the error case should be removed too?

I haven't setup a linux system to test if this works in linux. Google Gemini reported that natively capturing system audio via Electron's desktopCapturer module does not work on Linux. The issue is in the Chrome Embedded Framework in Linux. Capturing video should work in MacOS, Windows and Linux.
