A computer system that is in communication with a display generation component and one or more input devices, the computer system comprising:

• one or more processors;
• memory;
• and
• one or more programs, wherein the one or more programs are stored in the memory and configured to be executed by the one or more processors, the one or more programs including instructions for:
• while a user of the computer system is participating in a communication session with one or more participants, and while displaying a representation of the one or more participants in a three-dimensional environment that is visible via the display generation component from a respective viewpoint of the user, receiving, from a computer system of one of the one or more participants, an indication to display a shared content item associated with the communication session in the three-dimensional environment;
• and
• in response to receiving the indication to display the representation of the shared content item in the three-dimensional environment and in accordance with one or more criteria being satisfied, displaying the representation of the shared content item at a first location within the three-dimensional environment, wherein the representation of the shared content item, when displayed at the first location within the three-dimensional environment, partially occludes the representation of the one or more participants from the respective viewpoint of the user.

A non-transitory computer readable storage medium storing one or more programs, the one or more programs comprising instructions, which when executed by one or more processors of a computer system that is in communication with a display generation component and one or more input devices, cause the computer system to perform a method comprising:

• while a user of the computer system is participating in a communication session with one or more participants, and while displaying a representation of the one or more participants in a three-dimensional environment that is visible via the display generation component from a respective viewpoint of the user, receiving, from a computer system of one of the one or more participants, an indication to display a shared content item associated with the communication session in the three-dimensional environment;
• and
• in response to receiving the indication to display the representation of the shared content item in the three-dimensional environment and in accordance with one or more criteria being satisfied, displaying the representation of the shared content item at a first location within the three-dimensional environment, wherein the representation of the shared content item, when displayed at the first location within the three-dimensional environment, partially occludes the representation of the one or more participants from the respective viewpoint of the user.
