python request and MSL is not working with azure protected URL

i have some url where i need to do web crawling and it is protected by azure SAML protected. i have got the access token but still, request.get method return me to the redirected SAML login page content i use python masl library for azure SAML authentication.

import requests
http_proxy = "http://my proxy setting here"
https_proxy = "http://my proxy setting here"
proxyDict = {
"http": http_proxy,
"https": https_proxy,
}
app = ConfidentialClientApplication(
"my azure client id here",
"my azure sceret id here",
authority="https://login.microsoftonline.com/my tenat id here", proxies=proxyDict)
user = 'myuser@hotmail.com'
pwd = 'mypassword'
scope=['User.Read']
access_token = app.acquire_token_by_username_password(username=user, password=pwd, 
 scopes=scope)
url = 'https://my web site where i need to do crawling'
api_head = {'Authorization': 'Bearer ' + access_token['access_token']}
response = requests.get(url, proxies=proxyDict, headers=api_head)

but in return i get the login page url content only not the page i requested. also if i try to use some Microsoft graph that work fine and return the data. Not sure what is wrong in this flow any help is appreciated.

Thanks in advance..
