MTG arena.. can anybody tell me why this happened?

I was playing a brawl game on arena with my commander quezar, with who whenever I draw a card I gain 1 life and my opponent loses 1 life. I also had on the battlefield the card “cleric class” at level two which means every time I gain life I gain 1 additional life and every time I gain life I put a +1/+1 counter on a creature I control. I was getting low on health and needed a boost so I played the card “days undoing” which says that each player shuffles their graveyard and hand into their library, then draws 7 cards, and if it’s your turn, end your turn. I played that card thinking I would gain 14 life and put 7 counters on my creatures since I drew 7 cards. But, nothing happened. I drew my 7 cards and none of my triggers went off. Does this have something to do with ending my turn? I wouldn’t think so since the triggers would go off if I drew during somebody else’s turn as well
