Does anyone have an example of how to formulate a request to update a pagelist inside a case using pega API JSON request , the below is given as example but is difficult to underatnd  {   "content": {},   "pageInstructions": [     {       "instruction": "APPEND",       "target": "myPageList",       "listIndex": "3",       "groupIndex": "Customer",       "listMoveToIndex": "5",       "content": {}     }   ] }
