The doorway on the left has a set of glass shelves, and the other one, the one on the right is just, from here just looks like a hallway. Take one step into the hallway. Take two steps into this hallway until it dead ends into a wood endpiece with white rocks on top, and it has a screen. So right before the end of the of the wood, tall wood box full of rocks, is your end point.
