我在 GA 上注册我的项目，接收并保存 client_secret.json 并创建 credentials.json 完成注册设备的所有步骤：https ://developers.google.com/assistant/sdk/guides/library/python/embed/register-device
并尝试在 googlesamples-assistant-hotword 上进行测试：
googlesamples-assistant-hotword --device-model-id 'bridge-xxxxxx-bridge-igzdf5' device_model_id: bridge-xxxxxx-bridge-igzdf5 device_id: 0CE81A09B69F736CBC03F8C93F659C55
This device is not registered. This means you will not be able to use
Device Actions or see your device in Assistant Settings. In order to
register this device follow instructions at:
https://developers.google.com/assistant/sdk/guides/library/python/embed/register-device
ON_MUTED_CHANGED: {"is_muted": false} ON_START_FINISHED
什么是错的？
