Get Text using a Connector in an orchestration

I have setup a connector to Get_PO_Header_Text using doc https://docs.oracle.com/cd/E53430_01/EOTRS/op-v2-file-gettext-post.html. When I test the connector, I see that is it fetching the text.

However, I am do not understand how I get the text to output in my orchestration

Below is the text that is fetched from my order header when testing the connector - there are two text attachments. How can I output this text?

{

 "textAttachments": [

  {

   "text": "test attachment 1\n2nd line of attachment 1",

   "isRTF": false,

   "sequence": 1,

   "itemName": "Text1"

  },

  {

   "text": "test attachment 2\n2nd line of attachment 2",
