Some people collaborate better in person, some don't. I work with people (deliberately) who collaborate better via text chat. We sometimes jump on a call with a screen share, but that is rare. I have tried everything over the past 30+ years and find there are some people who just 'need' the office as they thrive there, but mostly I found that people who insist on office hours and say they are more productive are just really not very good at what they do and compensate for that with an external cabaret of 'work' which really doesn't work at home.
By the way, LLMs really helped us here; we chat with a bot reading and extracting everything and storing it conveniently so it won't get lost for later.
