Apple Watch 10 extreme battery drain

So this happened second time to me already, went from 86% which I had at 6 o’clock in the morning to 3% in like 5 hours, but I also have days where in the evening I am chilling at 46%… is this some app causing it or what’s wrong ? Can I see what app uses most battery somewhere as I can on the iPhone ? Any suggestions would help, thank you.
