After installing the apps, Workplace users can access messaging features like screen and file sharing, video calling, and private and group messages. Facebook said it also plans to add group video calling to the platform in the coming months.
In addition, Both mobile and desktop apps have redesigned interfaces to make them functionally similar to Facebook's flagship social networking app.
