  2. Open the desired app folder, and edit the config.json file using a text editor (for example, Notepad++.)
  3. Search the file for the widgetOnScreen segment.
  4. Find an empty positioning element or the last section of the segment, and add the following code.
     
    {
            "position": {
              "left": 205,
              "top": 45,
              "relativeTo": "map"
            },
            "placeholderIndex": 1,
            "id": "_8"
          }

    The following is an example of the final code snippet.
