Broadcast extension

The Broadcast extension works in two ways: it allows you easily capture any
tab, application, or screen and add annotations over the top of it. Once you
have captured the content, you can then download it as an image to your
device for later use

You can also use the extension with the Broadcast web app to add
annotations over a live screen sharing session with up to 40 people. To start
