You can filter the results by request status and staking position ID. The registration is processed asynchronously and may take some time to complete. It is recommended to implement automatic monitoring and handle the registration on time. If the registration request fails, please check the error message and resolve the issues before resubmitting the registration request. For more information, refer to [Babylon's official doc](https://github.com/babylonlabs-io/babylon/tree/main/docs).
