Slack -- which now has 5 million daily active users overall and 1.5 million users that are paying for the service -- said screen sharing is an extension of its native calling feature, which can be accessed from any channel or direct message.
To use Slack screen sharing, start a call as usual, tap the phone icon at the top of the screen and then hit the new "share screen" button. Participants on the call will be able to see the entire shared screen including the cursor, but Slack notifications will be muted to prevent any accidental over-sharing.
Slack has been steadily rolling out new platform features over the last two months. In April, Slack added clickable drop-down menus that let people complete more complex workflows inside the app. The company also recently rolled out refined admin controls for guest access and profiles, as well as its first AI search feature.
