In Prey (2017), there is side quest
to escape Talos-1 station, given by operator December.
Eventually, quest leads you to apartments of Alex Yu in living quarters section of station, to find key, which is hidden "on the data tower, near chair", so quest mark is displayed on Alex Yu apartments.
I've searched whole apartments several times, but I have no idea, what I should look for, and I can't find anything. So, what should I look for?
