Add Starbucks card from apple wallet to Starbucks app

I have a Starbucks gift card in my apple wallet and not in my Starbucks app. I can not add the card manually because I need the 16 digit card number AND the 8 digit card security code and the wallet app only shows the 16 digit card number. I tried to share it and it still only shows the card number and no security code. Is there anyway to look at the cards information in apple wallet or something to get the 8 digit security code number ?!!!
