-This opens a LiveKit meet session with the robot, returning an SFU endpoint, WebRTC token, and a join URL.

+```bash
+menlo robot connect              # Interactive selection

+
+Same as `menlo config default-robot`. Sets the default robot for the CLI.

+```bash
+menlo robot snapshot                         # Use default robot
+menlo robot snapshot --robot-id <robot-id>  # Use specific robot
