Thank you! And yeah, we totally hear the need for highlighting scannable areas. For the duration of the jam, we've included a walkthrough if you ever want to go back and finish the story :)
The monitor image has a Volume enabled with the following overrides: Motion Blur, Lens Distortion, Bloom, and Chromatic Aberration. It outputs to a render texture with the URP lit shader with a high smoothness, so it picks up a specular reflection from a single, carefully placed point light. The illusion is helped a bit with making the inner edges of the monitor model curved as well.
