The Cambly screen sharing extension for Google Chrome can be installed from the Chrome Web Store.
Once the screenshare extension is installed, you'll occasionally see a "Share Screen" button in the bottom right while working with students. We're only turning it on for a few students at a time, so you won't always see it initially. There's a lot of potential uses for screen sharing like sharing articles from the blog, sharing a whiteboard, and lots of others we probably haven't thought of. As always, we'd love to hear how screen sharing works for you.
