Can't get the topics to work for realsense d455 camera (RT-DETR)

[HariKrishnan06082k]

Hi I'm currently running the pipeline for getting realtime inference from realsense d455 camera for the following tutorial. Refer link below:

https://nvidia-isaac-ros.github.io/repositories_and_packages/isaac_ros_object_detection/isaac_ros_rtdetr/index.html#quickstart

I have a problem getting the normal realsense2_camera namespace topics to be exactly mapped to whatever is needed for the launch fragments of isaac-ros-example-realsense binary package:

sudo apt-get install -y ros-humble-isaac-ros-examples ros-humble-isaac-ros-realsense

How would I ensure that I make those remappings properly based on this tutorial as I found it to be working fine for rosbag.
