In order to share your screen, you first need to start a call in Slack. If you want to give Slack screen sharing a try, however, then Slack does offer a 30-day no-obligation trial to allow you to try out the premium features. A subscription is also required if you wish to use screen sharing. Whilst you can use the free version of Slack for things such as voice calls and one-to-one video calls, a paid subscription is required for additional features such as group video calls. We’ll explain how to set up and use Slack screen sharing below to help you get started. There’s even the option to draw on the screen in real-time, allowing you to make your explanations even clearer. This allows anyone else in the call to see exactly what you’re doing on your screen, so you can talk them through it step-by-step.

The good news is that you can make your life a whole lot easier by sharing your screen during a Slack call.
