Locating Electrical Outlet Behind Kitchen Cabinet?

I’m currently trying to install an over the range microwave, but I realized that the contractor likely put up a my kitchen cabinets over the outlet itself. Without having to remove the entire cabinet or pulling out the entire back panel, is there a good way to locate the outlet?

I’ve seen some recommendations for a stud finder with AC detection or a non-contact voltage tester, but wanted to check if someone had any insight into this issue. Thanks so much!
