Does anyone know the name of this short story?

I use an app called Volume to read on my phone. Everyday there is a curated list of articles and stories that are featured based on you interests. I remember reading a story once. It was told in the author's perspective, although he or she did not reveal much detail about them and only wrote in first person.

The story was about them getting a job at the school. This school also had a a storage closet that was left very crowded and disorganized by the old janitor. Overtime, the protagonist cleans the room little by little. People end up surprised when they pass by the room and discover how spacious and organized it was becoming, but the protagonist wasn't as surprised as much anymore. The story ends with the protagonist finding a window when the room was finally not as cluttered as before.

It was a very mundane setting but was filled with a lot of contemplation as the protagonist scours the room. They may comment on how tedious it was, what they find, or the things they assume of the old janitor based on the stuff he kept. It was basically hinting on themes of progress. How little by little, efforts can compound as we go along in finishing tasks or journeys.

The app doesn't track your reading history, and I've already searched so hard to find it but couldn't. I remember the story being a published article. I'm not quite sure anymore what the title was, hopefully someone can help me identify it.
