Python Requests: Generating a specific token (__cf_bm)

I recently got into using the requests library.

What I am doing: Posting a request to a url, parsing the response html for an element. Here is what my current code looks like:

import requests
client = requests.Session()
client.get(URL) #the url of the site
csrftoken = self.client.cookies["csrftoken"] # the payload requires the token
r = client.post(url=URL, data=dict(csrftoken=csrftoken, download=link)) 
for line in r.iter_lines():
  if b"id_to_be_located" in line:
    print(line)

I'm not getting the desired response. I did some digging are here is what I found out.

1. The response I get is of the original URL not the one that I'm supposed to get after the request.
2. Tried: stream=True and allow_redirects=True no luck. Cross-checking the post url, the payload
3. Finally I tried comparing the bare cookies of the python session and a browser session, turns out I have a cookie missing, namely __cf_bm.

Is there a way to generate that specific cookie? Obviously, I can try using selenium, but that's way too much of a small task. I don't know if I should be writing the name of the website, I'm open to questions and suggestions. Thanks
