At the moment there is no working ingame NWS Binding for that bird. The “Set NWS Limit” just triggers animation but not the actual limit. If this is a bug or a limitation is hard to say. At the moment you need to Click the Button with Mouse/Controller or use an external script to trigger the B Event:
