I'm using the HTML5 Telerik Report Viewer R2 2017 for Angular 4.
I was able to set the authentication token through the report viewer's property authenticationToken. But when I load the report in my browser, no Authentication Bearer Token is generated in the Request produced by the report viewer.
The following is the Request Header where the token is supposed to be generated:
