The disclosed techniques optimize the use of computing resources and user engagement by dynamically displaying a group of users of a communication session within a designated display area where each user of the group each share a common activity factor. For example, participants can be part of a group displayed in a certain section of a user interface or on a particular display screen if they each share a location, a role, a set of permissions, a team, a contribution level, etc. A system can also allow users of a group to exclusively control content that is displayed within a designated display area associated with the group. By dynamically displaying a group of users and content they control within designated display area by the use of a common activity factor, a system can improve user engagement by enabling users to readily identify people of interest.
