What is the process of creating the newly channeled books?

I had this question randomly pop up in my head of how the new books are being made. Does Andrew channel Elan verbally and someone else types it down? Are there funny conversations in between that would not be in the book? 😄 Or does Andrew write the book alone and it's more of an "inner" channeling? Also how much does Elan take part in the creation of it? Does he share what the book title could be or does he help design the book cover? 😄 Just curious. ☺️
