Remember after first map loss she said "They just played better than us, props to them" even though they lost a heavy lead which most coaches would chalk upto them throwing? That's the way to go about it imo. Sometimes that's just how it is, the opponent is just better.
If you are too hung up on yourself you become hindsight harrys and start blaming everything you did in a match. That's how you lose confidence as a team and start playing to not lose instead of playing to win. That's the recipe for losing.
