What is Presenter Overlay in macOS Sonoma, how do you use it and how does it work?

Sharing your screen during a video call is a great way to show other people on the call exactly what you’re talking about. Whether it’s a document you’ve been working on, or simply showing your grandma how to sign in to Netflix, sharing your screen can make your explanations significantly easier. One downside is that when you’re sharing your screen, you disappear from view, making the call feel less personal and a little detached.
