Then thats on you. Our team collaborates with three time zones. There was never full work from the office. Yet we still collaborate fine and share these things when we meet over zoom. Maybe your group should have a regular meeting where if people want to sign up and share what they’ve been working on they may do so. We were doing that even when our side of the group was in person because thats about the only way to get the full scope of someones work: a 45 min end to end presentation where you can ask questions, not chitchat in the hallway.
