I'm unable to get x-Token-Expired header in client-side in fetch request. I have added the header from server-side

filterContext.HttpContext.Response.Headers.Add("x-Token-Expired", "true");
filterContext.HttpContext.Response.Headers.Add("Access-Control-Expose-Headers", "*");

In client-side, looping through the headers , I am not able to get x-Token-Expired header.

 let tokenExpiredHeader = response.headers.get('x-Token-Expired');
 for (var pair of response.headers.entries()) {
   console.log(pair[0] + ': ' + pair[1]);
 }

This is what I get in console

Although the above said header is present in response header list

Thanks in advance !!
