If someone has shared their calendar permissions with you, you will be able to check their calendar directly without needing a conversation.
Imagine someone wants to book some time with you. Offer to look up the calendar and book in time straightaway.
❌ Bad Example - "Try calling him."
✅ Figure: Good Example - "Sure, I'll just look up Adam's calendar and see when he's free. Obviously, it's not a good idea to call Adam now as he is on a plane."
