Is cross validation automatically implemented in auto model?

Hi all,

I saw from a few posts that if you use auto model, cross-validation is already implemented in it (see below under Posts), can someone please confirm?

When i use auto model and i press on the "Open process", and then look at the "create validation set" in the "basic processing" section, it shows split data, not Cross-validation (picture attached). I'm unsure if I'm looking in the right place.

Can someone please let me know? thanks in advance.
