docs: Instantiate a new ClientConfigureRejectTransaction from a dict
          (generally from loading a JSON response). The data used to instantiate
          the ClientConfigureRejectTransaction is a shallow copy of the dict
          passed in, with any complex child types instantiated appropriately.
