i'm trying to edit a user selection a user did in a dialog. This dialog is part of an executable process in the ARIS Process Governance. 

Unfortunately, i can't find a possibility to add users to this selection or to delete existing ones via localService or report. 

Can someone help me?

Many thanks in advance! 



For discussion, in this example i just want to add someone from UMC to an existing selection:

var me = userManagement.findUserByLogin("loginName");
var myDisplayName = me.displayName;
var myId = me.UUID;
function isUserChooserEmpty(selection) {
        return false;
        return true;

    var users = input.userSelection.participantGroup.participants.participant;
    users.add(me); //This is not working because the object is of type AInputXMLData. Here is the problem.
    output.updatedUserSelection = users;
    output.updatedUserSelection = "updatedUserSelection is empty";
