Right now, you're facing towards the wall. Turn left and move towards the white door which is in front of you. Now, turn slightly right and move forward and you can see an opened door on the left. Now, turn left and move towards the entrance of the room, which is on the left. From there, slightly turn right and move forward until you reach a large glass door in front of you. Pass through through the glass door and take a few steps, where you will be facing towards the glass railing and that is the end point.
