cookie implementation cfg needed

[ElijahFeldman7]

this is my current implementation:

cookies = load_spotify_cookies()

saver = JSONSaver()  

saver.data = {
        "identifier": SPOTIFY_EMAIL,
        "cookies":    cookies
}

instance = Login.from_saver(saver)
instance.login()

i am getting an error:
missing a required argument: 'cfg'

Where should the cfg be with cookies and what args does it need??

[ElijahFeldman7]

using
Login.from_saver(saver)
instead of the last two lines also didnt work
