Notify device app for a device-twin update (python)

I'm trying to notify my devices for changes in their device-twin. After reading almost all of Azure's documentation, I could not find any solution for notifying the device app for a device twin update directly and not by running a service that subscribers an event-hub, and sends the messages it receives to the device. Moreover, the python code supplied here by Azure for sending cloud-to-device messages- crashes. Does anyone have some successful experience with this kind of communication?

Here you go, from the official github repo.

async def twin_patch_listener(device_client):
        while True:
            patch = await device_client.receive_twin_desired_properties_patch()  # blocking call
            print("the data in the desired properties patch was: {}".format(patch))

# Schedule task for twin patch
asyncio.create_task(twin_patch_listener(device_client))
