formatting a column according to content type

hello everyone, I am trying to modify my display behaviors on a sharepoint list from the json and I would like to know if it was possible to define styles according to the type of the element: apply this style if it's a folder and another if it's something else, something like this:

"display": "=if(@currentField == '','none','flex')"

but with a type parameter this time.

Good day to you
