How to Read PX4GUID in a ROS 2 Node (PX4 1.15, uXRCE-DDS)

Hello,

I’m working on a ROS 2 integration with PX4 and I need to access the PX4GUID from within a ROS 2 node.

I’m running PX4 1.15 and using the uXRCE-DDS (PX4-ROS 2/DDS Bridge) for communication.
Is there a way to read the PX4GUID directly through the ROS 2 interface?

Thanks,
