How to see the users with whom you have shared your project?

Go to the Dashboard, and you'll see all projects that you're collaborating/working. Next to each project information (project name, and revision number), there's three dots (Figure 1) that by clicking on it, a dropdown with a few options will be displayed, such as Manage Revisions, Project Team, and so on (Figure 2).
