Can't log in to facebook using requests module

I'm trying to log in to facebook using requests module. Although it seems I've prepared payload in the right way but when I send it with post requests, I don't get desired content in the response. I get 200 status code, though. To let you know, If I get response accordingly, I should find my fullname within it.

I initially tried like the following:

import requests
from bs4 import BeautifulSoup
from datetime import datetime

link = 'https://www.facebook.com/'
base_url = 'https://www.facebook.com{}'

time = int(datetime.now().timestamp())

headers = {
    'User-Agent': 'Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/88.0.4324.150 Safari/537.36',
    'referer': 'https://www.facebook.com/',
}

with requests.Session() as s:
    r = s.get(link)
    soup = BeautifulSoup(r.text,"lxml")
    form_url = soup.select_one("form[data-testid='royal_login_form']")['action']
    post_url = base_url.format(form_url)
    payload = {i['name']:i.get('value','') for i in soup.select('input[name]')}
    payload['email'] = 'YOUR_EMAIL'
    payload['encpass'] = f'#PWD_BROWSER:0:{time}:YOUR_PASSWORD'
    payload.pop('pass')
    res = s.post(post_url,data=payload,headers=headers)
    print(res.url)
    print(res.text)

This is another way I tried which didn't work out either:

import requests
from bs4 import BeautifulSoup
from datetime import datetime

login_url = 'https://www.facebook.com/login/device-based/regular/login/?login_attempt=1&lwv=101'
time = int(datetime.now().timestamp())

headers = {
    'user-agent': 'Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/91.0.4472.124 Safari/537.36',
    'origin': 'https://www.facebook.com',
    'referer': 'https://www.facebook.com/login/device-based/regular/login/?login_attempt=1&lwv=101'
}

with requests.Session() as s:
    r = s.get(login_url)
    soup = BeautifulSoup(r.text,"lxml")
    payload = {i['name']:i.get('value','') for i in soup.select('input[name]')}
    payload['email'] = 'YOUR_EMAIL'
    payload['encpass'] = f'#PWD_BROWSER:0:{time}:YOUR_PASSWORD'
    payload['had_password_prefilled'] = 'true'
    payload['had_cp_prefilled'] = 'true'
    payload['prefill_source'] = 'browser_dropdown'
    payload['prefill_type'] = 'contact_point'
    payload['first_prefill_source'] = 'last_login'
    payload['first_prefill_type'] = 'contact_point'
    payload['prefill_contact_point'] = 'YOUR_EMAIL'
    payload.pop('pass')
    r = s.post(login_url,data=payload,headers=headers)
    print(r.status_code)
    print(r.url)

How can I log in to facebook using requests?
