	// capabilities on all media channels by default. You use the capabilities with a
	// set of values that control what the capabilities can do, such as SendReceive
	// data. For more information about those values, see . When using capabilities, be
	// aware of these corner cases:
	//   - You can't set content capabilities to SendReceive or Receive unless you also
	//   set video capabilities to SendReceive or Receive . If you don't set the video
	//   capability to receive, the response will contain an HTTP 400 Bad Request status
	//   code. However, you can set your video capability to receive and you set your
	//   content capability to not receive.
	//   - When you change an audio capability from None or Receive to Send or
	//   SendReceive , and if the attendee left their microphone unmuted, audio will
	//   flow from the attendee to the other meeting participants.
	//   - When you change a video or content capability from None or Receive to Send
	//   or SendReceive , and if the attendee turned on their video or content streams,
	//   remote attendees can receive those streams, but only after media renegotiation
	//   between the client and the Amazon Chime back-end server.
