What is the difference between the 'Export and Share' and 'Close Deal Memo' actions?

Thanks for the quick response, Woody! Here's what I have from the AI Assistant below. I understand the small differences e.g. ability to edit, view, etc. I'm struggling to understand how it impacts the investment process and what happens to the deal in the system after.

"Export and share a Deal Memo allows you to select specific sections to include or exclude before sharing it with others. Closing a Deal Memo finalizes it, creating a record in the Deal Memo Data Rooms, and notifies team members. Once closed, team members who haven't completed their scores can't see others' scores until they submit their own to prevent bias. For more details, visit Decile Group."
