I am trying to find a way of calling a function in an instance of an NG Client; primarily, this is to process a callback from another web page opened from that client.
The JSClient can be used for Headless Clients to use queueMethod() but I cannot find a way of getting a JSClient instance from the GetClientID() of an NG Client. The closest I can find is plugins.headlessclient.getOrCreateClient(), which is again only for headless clients.
The upshot being that I am seeking a way to call a function in a running instance of NG Client from a call received on the server; unless it is possible for an instance of NG Client to get a callback directly.
