I can only speculate, but perhaps it has something to do with something else we are able to engage with... [ He hums in thought, pausing to look around and remember. ] Trapdoors. Items strewn on the ground. And perhaps not everyone in this maze is lost like we are.

I've already attempted searching the file cabinets, but it seems like a waste of our time. Still, I haven't tried interacting with anything else I've listed.
