Unreal learning Hololens2 redemption code project incomplete

Hi,

I don’t know if this is the right place for this to ask but,

I just started this morning with the HoloLens 2 Mixed Reality Production for Unreal Engine course.

on the second chapter, the gaze and head interaction, we have to download a prepared project.
But the project is incomplete.

It only has the main map. Not the other assets.

Am i doing something wrong?
