• presenting a view of a first three-dimensional (3D) environment;
• obtaining data representing a second 3D environment, the data representing the second 3D environment based at least in part on sensor data captured in a physical environment of a second electronic device;
• determining portal content based on the data representing the second 3D environment and a viewpoint within the first 3D environment;
• and
• displaying, in the view of the first 3D environment, a portal with the portal content, wherein the portal content depicts a portion of the second 3D environment viewed through the portal from the viewpoint.
