Unsubscribe from an event. There was a previous subscription made with on.
Sample unsubscription code
const modeChangedCallback = (event) => {
//.....................................
};
sambaFrame.on('layoutModeChanged', modeChangedCallback);
//......................................................
//This will unsubscribe from the event, so the callback won't be invoked anymore
sambaFrame.off('layoutModeChanged', modeChangedCallback);
