World’s Game EAFC 27 Rewards

I’ve returned to the game after having not played since November. World cup hype got to me and I got the urge to play fut again. Conveniently, I saw that there are rewards to carry over to the next installment. But do we know what these rewards are? Also, all we have to do is play one game in the, “World’s Game,” mode? As well as complete the, “Journey of Nations,” objectives? Thanks for any help
