Per the documentation here: www.codesys.com/products/codesys-visualization/targetvisu.html to present a visualization on a display connected to the PC running the PLC runtime, I believe you'd right click on the visualization manager, add an object for the targetvisu, then select the start visualization and the visualization should take over the screen when the PLC is started. I will have to do some testing and might make another video. I'll have to setup a PC with a desktop linux distro that has a display manager. If it isn't as straightforward as I think, and I can figure it out, I may make another video showing how to configure the local visualization.
