Did you actually choose Diamond Medallion Choice Benefits? Looks like you are on a status match. Diamond status does not automatically provide lounge access (you have to choose it among the Choice Benefit options), but you won't have access to Choice Benefits until you complete the challenge. One of the Choice Benefits is a Guest Sky Club access benefit for people who already have Amex Plat or a Sky club membership. Amex Plat cardholders can bring in up to two guests for a fee, but they don't state what the current fee is.
