Various implementations disclosed herein include devices, systems, and methods that enable presenting environments including visual representations of multiple applications. In one implementation, a method includes presenting a view of an environment at an electronic device on a display. The view includes visual representations of a plurality of applications. The method further includes determining to provide a first application with access to a control parameter. The control parameter is configured to modify at least a portion of the view of the environment with virtual content, and the portion of the view includes at least a portion of content outside of a view of a visual representation associated with the first application. The method further includes restricting access to the control parameter by other applications which prevents the other applications from modifying the at least the portion of the view of the environment via the control parameter.
