Isolating Micro-ROS topics

When I add the line 'export ROS_DOMAIN_ID=47' to the bashrc file and then load Micro-ROS, my custom topics are not visible. However, when I comment out the ROS domain ID line, restart the agent, and reload Micro-ROS, my custom topics become visible. I'm stuck and unsure how to properly isolate my Micro-ROS topics without interference from the ROS domain ID and Can anyone provide guidance on how to properly isolate Micro-ROS topics in this setup?

Note:For Isolating the ROS2 topics using ROS_DOMAIN_ID is working fine.

Start by reproducing the setup with ROS_DOMAIN_ID=47 in bashrc, then compare topic visibility after restarting the Micro-ROS agent and reloading Micro-ROS. Done means custom Micro-ROS topics remain visible while ROS 2 topics stay isolated; the issue does not name a source file or test to run.
