Using the ICM Nash Calculator, if we call and win our equity would be 44.7%. If we call and lose, our equity is zero. If we fold, our equity is 35.9%. This assumes no one else calls.

If CO is on atc, our showdown equity is 85.2%.

EV of a call = .852*44.7 - .148*0 = 38.1
EV of a fold = 35.9

So, surprisingly, it's a call. It's also a call with KK, but not QQ.
