## No Topic Visible if running micro ros agent on Humble, but these are visible if the agent is running on Foxy

- Hardware description: Linux and ESP32
- RTOS: -
- Installation type: micro_ros_setup
- Version or commit hash: Humble

#### Steps to reproduce the issue
I have followed the tutorial from the links below:
https://micro.ros.org/docs/tutorials/core/first_application_linux/
https://micro.ros.org/docs/tutorials/core/teensy_with_arduino/

The issue is, if I run the micro ros agent on ROS Humble (both serial or udp), I don't see any topics and nodes related. But in -v6 I am able to see the data is publishing.

The thing is, I am able to subscribe it through node. But I am not able to see the topic list in the terminal.

I have tried unset ROS_DOMAIN_ID, set the same ROS_DOMAIN_ID, set the same RMW_IMPLEMENTATION, unset the RMW_IMPLEMENTATION. But nothing works.

Then I tried to use foxy to run micro ros agent (using docker ros-foxy), I am able to see the topic list on Humble. And I also able to echo it. as you can see the picture below


#### Expected behavior
I should be able to see the topic list, while the micro ros agent runs in the Humble.

#### Actual behavior
Unable to see the topic list, while the micro ros aget runs in the Humble.

#### Additional information
This is my env, even if I didn't set the same ROS_DOMAIN_ID, and didn't set the RMW_IMPLEMENTATION, if I run the agent on Foxy, it still work and detected on Humble 

まず、ROS 2 Humble 上の micro-ROS Agent で問題を再現し、説明されているとおり serial と UDP の両方を使って、その -v6 出力を Foxy Docker setup と比較します。報告にある ROS_DOMAIN_ID と RMW_IMPLEMENTATION のバリエーションを確認します。Humble 上で agent を実行したときに topics と nodes を検出でき、echo できれば完了です。
