The difference between body doubling and "working in an office setting" is mutual agreement to avoid distracting each other. I usually combine body doubling with a pomodoro timer, so 25-30 minutes and then a break. This isn't conducive to deep flow work, but it's great for getting your taxes done, booking a trip, researching a dreaded thing, reviewing a PR, etc.
