Postscribe(use to add 3rd party script) is not working: Angular 9 Universal.

[junaidbinsarfraz]

In Angular 7 Universal, I was able to add 3rd party scripts using postscribe (without any special settings). Now I am trying to use postscribe in Angular 9 Universal project like

if(this.isBrowser) {
    // ... my postscribe code here
}

but its giving below error

var work = window.document.createElement('div');
                           ^

ReferenceError: window is not defined

A server error has occurred.
node exited with 1 code.

In server.ts I have added

// for mock global window by domino
const win = domino.createWindow(template);
// mock
global['window'] = win;

Not sure why its giving this error, any clue? I am using "postscribe": "^2.0.8".
