Thanks for your help Neil.
I have two problems, the first is that the script uses window and document objects that are not supported by NeoLoad. How can I solve this problem? The second is that i have not received any information from the developers on how to use this function.

(function() {
(function() {
function a() {
if (!b.dialogArguments) return navigator.cookieEnabled;
document.cookie = "__dTCookie=1";
var a = -1 !== document.cookie.indexOf("__dTCookie");
document.cookie = "__dTCookie=1; expires=Thu, 01-Jan-1970 00:00:01 GMT";
return a
}
if (window.dT_) window.console && window.console.log("Duplicate agent injection detected, turning off redundant initConfig.");
else {
var b = "undefined" !== typeof window ? window : self;
a() && (window.dT_ || (window.dT_ = {
cfg: "#CONFIGSTRING#|auto=#AUTO#|domain=#DOMAIN#|rid=RID_#REQUEST_ID#|rpid=#RESPONSE_ID#|app=#APP#",
iCE: a
}))
}
})();
}).call(this);

(function() {
(function() {
function Kb() {
return ra ? new ra : sa ? new sa("MSXML2.XMLHTTP.3.0") : d.XMLHttpRequest ? new d.XMLHttpRequest : new d.ActiveXObject("MSXML2.XMLHTTP.3.0")
.....

and later in script :

var G = window;
if (!G.dT_ || !G.dT_.cfg || "string" != typeof G.dT_.cfg || G.dT_.initialized) G.console && G.console.log("Initconfig not found or agent already initialized! This is an injection issue.");
else if (!(navigator.userAgent && 0 <= navigator.userAgent.indexOf("RuxitSynthetic"))) {
var d = "undefined" !== typeof window ? window : self,
ra, sa, Z, db = [],
Da,
....
