Missing "list" field of the response body

Hey everyone! I was trying to create a basic flow using a custom API call for ChatGPT (chat-3.5-turbo). I get the response on “Block 3”(second block) which includes “choices” field that stores the answer from ChatGPT ( you can see the first image ). But when I am trying to add a CMS item ( Block 5 , third block) , I see that the only missing field is “choices”. Is there any way to reach "choices → message → content " without custom embedded code?
