How to use the scs.controller.apps function in scs

def dispatch(self, request, app, rest):
        gd = lambda m: getattr(request, m)
        queue, url = self.prepare_path(rest)

                         routing_key=queue["routing_key"])
        params = gd(method) if method in self.get_methods else gd("GET")
        data = gd(method) if method not in self.get_methods else None

        with producers[broker.connection()].acquire(block=True) as producer:

            result = webhook.apply_async((url, method, params, data),

def delete(self, request, app):
        return apps.delete(app)

def get(self, request, app=None):
        return apps.get(app).as_dict() if app else apps.all()
