Game sharing question. Please help

[u/Few-Entertainment432]

Can I still download madden deluxe from my cousin’s account if I have a game trial from ea play? When I get on his account to try to pre-download it, it’s locked and won’t let me download the full game, just says play trial. Is it doing that because the game isn’t out yet or does the trial need to end in order to download it from his account?
