11 . The method of claim 10 , wherein the one or more first voice commands are categorized in a plurality of different categories, and wherein the different categories comprise one or more of avatar movement, avatar actions, object movement, object actions, application settings, or system settings.

12 . The method of claim 10 , wherein the one or more first voice commands are labeled as one type of a plurality of different types, and wherein the different types comprise commands or queries.

13 . The method of claim 10 , wherein the one or more first voice commands available for search are based on a characteristic of the first user.

14 . The method of claim 10 , wherein the one or more first voice commands available for search are categorized based on one or more XR objects in the XR environment.

15 . The method of claim 9 , wherein the user interface overlay comprises a help hub to receive one or more queries from the first user.

16 . The method of claim 9 , wherein the user interface overlay comprises an index of the one or more first voice commands.

17 . The method of claim 1 , further comprising:

determining, based on an absence of detected action of the avatar of the first user with respect to the second XR object and a position of the second XR object within the field of view of the first user, to not invoke the attention system with respect to the second XR object.

18 . One or more computer-readable non-transitory non-volatile storage media embodying software that is operable when executed to:

render, for one or more displays of an XR display device, a first output image of first XR object and a second XR object within an XR environment in a field of view (FOV) of a first user, wherein the first XR object and the second XR object are interactable via one or more first voice commands by the first user, and wherein the first XR object and the second XR object each have a first form from a plurality of forms each corresponding to a corresponding attention state from a plurality of attention states;

detect an action of an avatar of the first user with respect to the first XR object;

determine, based on the detected action of the avatar of the first user with respect to the first XR object and a position of the first XR object within the field of view of the first user, to invoke an attention system with respect to the first XR object; and

render, for the one or more displays of the XR display device, a second output image of the first XR object responsive to invoking the attention system, wherein the second output image comprises a second form from the plurality of forms of the first XR object indicating a first attention state from the plurality of attention states and the second output image further comprises an indication identifying the first attention state and the first form of the second XR object indicating that the attention system with respect to the second XR object is not invoked,
