Access Request-Headers AFTER hitting the request

My question:
Is it possible to access request-header after the request is hit?

My pre-request script looks like :

var Cookie = null
pm.sendRequest("", function (err, response, options) {
    Cookie = options.cookies.members[0].value;
pm.globals.set("Cookie", Cookie);
pm.environment.set("Cookie", Cookie);
pm.request.headers.add({key: "Cookie", value: Cookie});

So basically I want to capture the auto-generated(auto-injected) Request-Header Cookie from the pre-request script and use it in the actual request

I’ve already tried:

  • options.cookies.member
  • request.headers
  • pm.cookies
