This information is available in all the hand historys. If you went to showdown on a hand than technically anyone dealt in that hand has the right.
From wiki "Any player who has been dealt in may request to see any hand that is eligible to participate in the showdown, even if the hand has been mucked."
Roberts Rules of Poker 11 - The Showdown "5. Any player who has been dealt in may request to see any hand that was eligible to participate in the showdown, even if the opponent's hand or the winning hand has been mucked. However, this is a privilege that may be revoked if abused. If a player other than the pot winner asks to see a hand that has been folded, that hand is dead. If the winning player asks to see a losing player’s hand, both
hands are live, and the best hand wins."
