UI action Script help to convert incident to HR case

[NARENDRA KAMMIL]

Hello Is it possible to achieve this use case ?

When on an Incident up on clicking UI action (convert to HR case) it should land on HR portal page and user can select any ITEM on that HR portal . up on creating HR request the incident should be closed complete and Parent of HR case should be set as Incident 

Below is the code I am using , we have similar user case for request , instead of Portal it will redirect to Native view and is working fine.

UI action code for create HR case ( which is only working till redirecting to portal) 

var reqFor = current.caller_id.sys_id;
var reqItem = '6ce192b84fbe6e40cc05334d0210c785';
var number = current.sys_id;
gs.addInfoMessage("Submitting this Case will close incident "+current.number);
var url ="esc?id=emp_taxonomy_topic_standard&topic_id=c12227ffc3655510c8157a4ce00131df"+"&sysparm_processing_hint=setfield:request.parent=";
url += current.sys_id;
action.setRedirectURL(url);

UI action code for create Request for Incident ( which is  working ) 

//Update saves incidents before going to the catalog homepage
current.update();
gs.addInfoMessage('Note: Your incident will be closed if you submit this request');

var url = "catalog_home.do?sysparm_view=catalog_default&sysparm_processing_hint=setfield:request.parent=";
url += current.sys_id;

action.setRedirectURL(url);
