How to access child element value according to below json structure.

Below is the dump data in json format, Would like to know how to access to Debug.log(text) in the children of the GameObject which is name "LoadButton" in the root;

               {
                     "name": "LoadButton",
                     "tag": "Untagged",
                     "layer": "UI",
                     "active": true,
                     "position": "(0.0, -325.0, 0.0)",
                     "image": "FspA04_menu01_Base",
                     "components": ["RectTransform", "CanvasRenderer", "Image", "Button", ],
                     "children": [{
                         "name": "Text",
                         "tag": "Untagged",
                         "layer": "UI",
                         "active": true,
                         "position": "(38.8, -14.0, 0.0)",
                         "text": "LOAD",
                         "components": ["RectTransform", "CanvasRenderer", "Text", "Outline", ],
                         "children": []
                     }, ]
                 },

I think I was able to use GameObject loadbtn = GameObject.Find("LoadButton"); to get the root object, then I would like to know how to display the other json listed elements under this game object.

thanks.
