Converting CompletableFuture

i have an User Class and i want to retreive from CompletableFuture<Optional>

        CompletableFuture<Optional<User>> userCache = plugin.getBPApi().getUser(player.getUniqueId());
        User user = userCache.get();
        return String.valueOf(user.getTier());

But when i compile it throws the following error:

java.util.Optional<io.github.battlepass.objects.user.User> cannot be converted to io.github.battlepass.objects.user.User

What i'm doing wrong ?
