Update Security Token in Report Service

The Js Viewer allows to specify a security token during creation. However, sometimes you may need to change a security token at run time. To do so, you should use the onRequest handler as demonstrated in the example below:

const viewer = GrapeCity.ActiveReports.JSViewer.create({
  element: '#root',
  reportService: {
    onRequest: (init) => alert(init.credentials),
  },
});
