Instant messaging is not specifically a feature or technology associated with the infrastructure or operational aspects of a connected golf course. Connected golf courses typically utilize advanced technologies like 5G, location sensors, and underground fiber to enhance the playing experience, manage the course more efficiently, and provide various services. Instant messaging, while it could be used for communication on the course, is not unique or specific to the concept of a "connected" golf course in the way the other options are.
