The side panel sends messages to the main stage using `notifyMainStage()`, while the main stage uses `notifySidePanel()` to send messages to the side panel. To receive messages, add-ons must subscribe to the `frameToFrameMessage` callback. Messages are participant-specific and delivered once; the receiving panel must be open and subscribed. Payload size limitations apply. The Animation sample add-on demonstrates this functionality.\n"]]
