If you want to share your screen on Zoom, you can also share just a part of the screen.
You don't have to share your whole screen with the other Zoom meeting attendees. You just share part of it, so that you don't show unnecessary or sensitive information.
You can limit it to a specific window, or even share a portion of your screen using a resizeable rectangle window.
To do that, click on Share, then Advanced, and then Portion of Screen.
Sharing your screen is a great way to work together, especially if you're working from home and missing the face-to-face collaboration.
