What does "Share to notes" mean in Teams AI meeting recap?

On the Teams Premium introduction page, there is a "Share to Notes" button in the AI Notes area. However, it is not mentioned in any of the blogs or articles explaining how to use this feature. This discrepancy is quite confusing.

Can someone please clarify how the "Share to Notes" functionality works?
