const StyledTreeItem = withStyles((theme) => ({

      "organizationalUnitName": "C",
      "organizationalUnitsList": [
        {
          "organizationalUnitId": "",
          "organizationalUnitName": "D",
          "organizationalUnitsList": [
            {
               "organizationalUnitId": "",
               "organizationalUnitName": "e",
            }

        } …
