Image visualization issue using Visualization Package

    I have two PCs, one with Ubuntu 20.04 and a RealSense D435 publishing on ROS, the other with Windows 11 and Unity 2022.3.6f1. I'd like to see the live stream of the video from the RealSense in Unity. I'm using ROS-TCP-Connector to enstablish the connection between ROS and Unity and the Visualizations Package to visualize the incoming informations from ROS.
    To see the video I have selected the "/camera/color/image_raw" topic.
    When I press Play, I can see the incoming video in the Unity Game Window, but just in a widget, not really integrated in the scene. Instead, I would like to see the video directly in the Game, to stream it after in a VR HMD (Varjo Aero). I have tried to attach the "Image Default Visualizer" script to a GameObject (a plane), because I thought it was necessary to integrate the video in the Scene, but it didn't work. Could you give me some advice? Am I missing some steps?
