What’s a Business Expert?

Ed is not sure really as the question is somewhat vague.  If you ask it very softly, however, (and we all know from The Times crossword this will involve a “pp” somewhere) you get WhatsApp Business Expert. Now I know what one of those is as Lucy Anderson is one and she would like to connect with our director Mr Close

Regarding what a WhatsApp Business Expert actually does, on the other hand, I remain firmly in the dark so if your are reading, Lucy, give Closey a clue before he accepts or not.
