Publishing Radar Point Cloud Data

Isaac Sim Version

4.2.0

Operating System

Ubuntu 22.04

I want to publish RTX Radar to ROS2. I do not know how to generate an Omnigraph for this task. I have a graph like below:

I do not know what I am missing in the graph right now, the ROS2 topic is published, but with no information in it. (I can see it in the ros2 topic list but there is no data in it)
