How to pass authorization on the site using the requests library (Python 3.6) if the links are generated by js?

Question

Python

Please help me understand the page code https://pfizer.miflib.ru/auth/#/login

I'm trying to log in to the site using python and the requests library:

import requests

LOGIN = ''
PASSWORD = ''

login_page = 'https://pfizer.miflib.ru/auth/#/login'

headers = {'User-Agent': 'Mozilla/5.0 (X11; Fedora; Linux x86_64; rv:48.0) Gecko/20100101 Firefox/48.0'}
payload = {'action': 'post',
           'email': LOGIN,
           'password': PASSWORD
           }

with requests.Session() as session:
    s = session.post(login_page, data=payload)

    print(s.text)

However, instead of going to the catalog page, I constantly return to the authorization page.

Judging by the html code of the page, links for the transition are formed using javascrypt, but I can’t figure out where this happens and where the redirect goes.

I would be grateful if you point out errors or give advice.
