I am working with a Turtlebot 4 (that has Ubuntu 20.04 and ROS2 Galactic). I want to visualize pointcloud data in Rviz. After launching Rviz, I added pointcloud and pointcloud2 from Add option. But it shows an error "no topic to subscribe". Anyone knows in which topic pointcloud data is published? Or how do I access pointcloud data?
