Drf channels

I want to filter the model information pass down from my consumer.py using Django rest framework channels , I hope I get help here .

class ConsultationConsumer(ListModelMixin, GenericAsyncAPIConsumer):
queryset = Consultation.objects.all()
serializer_class = ConsultationSerializer
permission_classes = (permissions.AllowAny,) # Note the trailing comma

async def connect(self):
    await self.model_change.subscribe()  # Ensure model_change is defined
    await super().connect()

@model_observer(Consultation)
async def model_change(self, message, observer=None, **kwargs):
    await self.send_json(message)

@model_change.serializer
def model_serializer(self, instance, action, **kwargs):
    return dict(data=ConsultationSerializer(instance=instance).data, action=action.value).. 

Instead of getting all objects from the query set I want to filter it
