Microsoft Lists forms and the modified information

Question

I have a list that I added the built-in Modified, Modified by, Created, and Created by columns to. The information shows when viewing the list. I want to add that information to the footer of the form when someone opens the list item to edit it. I used the same JSON code i used in my header to show a person's first and last name, but it will not work when I try using the Modified, Modified by, Created, and Created by column names. It will work if I use any column that I created.

Is there some code I can use in the footer of the form to add Modified, Modified by, Created, and Created by information?
