How to open created record?

I have created a custom "create order" button on quote and created an action to populate details from quote to order

I triggered action using javascript

function createOrder(){
debugger;
guid = Xrm.Page.data.entity.getId();

var parameters = {};
var quote = {};
quote.quoteid = guid; //Delete if creating new record 
quote["@odata.type"] = "Microsoft.Dynamics.CRM.quote";
quote["transactioncurrencyid@odata.bind"] = "/transactioncurrencies(00000000-0000-0000-0000-000000000000)";
quote["pricelevelid@odata.bind"] = "/pricelevels(00000000-0000-0000-0000-000000000000)";
parameters.quote = quote;

var req = new XMLHttpRequest();
req.open("POST", Xrm.Page.context.getClientUrl() + "/api/data/v9.1/cr4a6_CreateOrder", false);
req.setRequestHeader("OData-MaxVersion", "4.0");
req.setRequestHeader("OData-Version", "4.0");
req.setRequestHeader("Accept", "application/json");
req.setRequestHeader("Content-Type", "application/json; charset=utf-8");
req.onreadystatechange = function() {
if (this.readyState === 4) {
req.onreadystatechange = null;
if (this.status === 204) {
alert("success");

} else {
Xrm.Utility.alertDialog(this.statusText);
}

}
};
req.send(JSON.stringify(parameters));

}

This code is creating a new order record in the background but i need to open that from on click of that same button.

Can anyone please help me.

Thank you.
