def fetch_access_token(client_id, client_secret, authorization_response, token_url):
    from oauthlib.oauth1 import OAuth1
    from requests_oauthlib import OAuth1Session

    # Create an OAuth1 client
    client = OAuth1(client_id, client_secret)

    # Create an OAuth1Session with the client and the authorization response
    session = OAuth1Session(client, token=authorization_response)

    # Fetch the access token by making a POST request to the token URL
    token_response = session.post(token_url)

    # Extract the access token from the response
    access_token = token_response.json().get('access_token')

    return access_token
