Please take a look at this post for the addition of Iz*One/Loona/(G)I-dle, whom some regard as 3.5th Generation.
Itzy just started touring, and probably has around 50K attendance so far, though their Checkmate tour is continuing into 2023 with eight more shows. StayC hasn't done any concerts as far as I know, but Aespa did have a few "Synk" showcases.
Aespa will probably have a higher attendance than most of the groups on this through fanmeets/showcases alone I'd imagine
