Hello. I am trying to follow this tutorial to add a new layer to my cost map. costmap_2d/Tutorials/Creating a New Layer - ROS Wiki

According to the tutorial, an obstacle appears 1m in front of the robot, but I don't know how to see it. (e.g., rviz.) The environment I'm working in is ROS Melodic.

This is a rudimentary question, but thank you for your help.
