Magic Leap 2 has a media player that can apparently be used in Unity, however, I understand the guide provided. I'm not able to get this in the Unity scene.

The website that you have linked is for the magically porn have you tried the magically to media player behavior component?
You can see the example in the magically unity example project version 1.12.0
