Authentification via OpenID

I'm trying to write a small script (Python) to see when my BahnBonus points are going to expire. However, as a newby to web-programming I struggle to obtain the bearer token from the bahn-login.

Do you have any hint on how to proceed, or where to look at?
I did not really find a lot of helpful information on this process, however I also don't expect you to give basic tech support.

import openid
import requests
from bs4 import BeautifulSoup
from getpass import getpass

auth_url = 'https://auth.businesshub.deutschebahn.com/auth/realms/kubi/protocol/openid-connect/auth'

if __name__=='__main__':
    session = requests.Session()

    params = dict(scope=          'openid profile user:read user:write',
            client_id=     'kubi',
            redirect_uri=   'kubi://authentication/redirect',
            response_type=	'code')
    
    res1 = session.get(auth_url, params=params)
    assert res.ok, 'could not get auth url'
    login_soup = BeautifulSoup(res.content.decode(), 'html.parser')
    login_form = login_soup.find(id='kc-form-login')
    post_url = login_form.attrs['action'] # this is the POST url of the login form, e.g. https://accounts.bahn.de/auth/realms/db/login-actions/authenticate?session_code=XX&execution=XX&client_id=mob_esuite&tab_id=f'
    
    username = input('Please enter username:\n').strip()
    password = getpass('Please enter password:\n').strip()

    res2 = session.post(post_url, data={'username':username,
                                       'password':password})
    # res1.content==res2.content, mostly same website gets returned?

probably it might be better to write this in JS after all?
