TEST INSTRUCTIONS

1. Download the build from this PR
2. Open it and go to the pravus.dcl.eth world
3. Once inside the scene, confirm that every time you press the E key, you switch between these 4 cameras (you won't be able to confirm the exact FOV value, just confirm that the zoom increases and in the end you return to the normal cam):
   • Normal character camera
   • Camera with FOV 45 (distant camera)
   • Camera with FOV 30 (distant camera with more zoom)
   • Camera with FOV 15 (distant camera with more~more zoom)
4. Change again between the cameras but this time confirm that when a virtual camera with zoom is active, if you leave the scene, you return to your normal character camera, and if you enter again, the virtual camera becomes active again.
