Download OOXML / Excel file with ticket authentication.

[Bucapps]

Hi, I've made all the process to get the url to download my file but when I get the qUrl I can't  just download the file using node. 

// Generate Sheet with data.
    var sheet = await app.getObject('e86fbce8-3aa3-4be0-8081-d55a1f4cd531')

    //Generate download link
    var exportResult = await sheet.exportData("OOXML", "", "export.xlsx");
    console.log(exportResult);

under exportResult I got 

{ qUrl:
   '/tempcontent/ABCD/fileName.xlsx?serverNodeId=nodeId',
  qWarnings: [] }

  and im stuck at the point of download. 

if I concatenate the url of my qliksense url with the qUrl and paste it in the browser it download the file. but I need to download the file from the Node server. 

I use ?QlikTicket=abcd1234 to authenticate. 

Can I use this session to download the file ?

const session = enigma.create({
        schema,
        url: `https://${qsAppHost}/app/engineData?QlikTicket=${qsTicket}`,
        createSocket: (url) => new WebSocket(url, {
            headers: {
                'X-Qlik-User': `UserDirectory=${encodeURIComponent(qsQpsTicketBody.UserDirectory)}; UserId=${encodeURIComponent(qsQpsTicketBody.UserId)}`,
            },
        }),
    });
