To spawn network objects and destroy them as well, you should use the special Network.Instantiate and Network.Destroy methods (of the Unity Network class). To make them show in FlowCanvas, please add the Network type in the Preferred Types Editor list and then you will be able to use all Network class methods and properties 🙂
Let me know if that works for you.
(PS: The new version will have a search field for the Preferred Types Editor)
