One key role for a manager is being able to detect who's feeling unmotivated or trying to bullshit you or has something going on in their life that's affecting their work, so that you can dig in to understand more and address the issues proactively. When you casually see people in person every day throughout the day, it's easier to notice when someone's demeanor changes, vs. mostly talking on slack and having a couple of zoom meetings per week.

I didn't catch the question but I will attempt to answer based on what I understand.

Role of a manager that will change significantly based on where the team is sitting - The ability to convey meaning and emotion over written comms and over video calls, to drive the team forward without being too mechanical about it.
