Secure Connect Gateway 5.12 rest API authentication not working

Hi,

I am trying to use python and its requests lib to automate some tasks of assigning devices to specific groups.

I have looked at the documentations (https://www.dell.com/support/manuals/sv-se/secure-connect-gateway/scg_rest_api_guide/user-authentication?guid=guid-255f66c6-65b2-4d79-85b1-36a9d0d474d8&lang=en-us)

But this does not work.
When i try to request a token with the way they refer to (Authenticate user by generating a JSON Web Token (JWT))
It just complains that my header lacks "authentication" headers.

here is what my test code looks like:

import requests
from pprint import pprint
import jwt



base_url = "https://:5700"

proxies = {
    "http": "",
    "https": "",
}

token_body = {
        "domain": "domain.se",
        "username": "username",
        "password": "password"
    }


# attemt 1
def get_token():
    url = base_url + "/v2/auth/token"
    token = jwt.encode(payload=token_body, key="secret")
    headers = {
        "Accept": "application/json",
        "Content-type": "application/json",
        "Authorization": "Bearer " + token
    }
    response = requests.post(url, headers=headers, proxies=proxies, verify=False)
    data = json.loads(response.text)
    # pprint(data)

# attempt 2
def basic_auth():
    url = base_url + "/v2/auth/token"
    headers = {
        "Content-type": "application/json",
        "Accept": "application/json"}
    response = requests.post(url, headers=headers, auth=("domain\\username", "password"), data=token_body, proxies=proxies, verify=False)
    data = json.loads(response.text)
    pprint(data)

# attempt 3
def basic_auth2():
    url = base_url + "/v2/auth/token"
    headers = {
        "Content-type": "application/json",
        "Accept": "application/json"}
    response = requests.post(url, headers=headers, data=token_body, proxies=proxies, verify=False)
    data = json.loads(response.text)
    pprint(data)

def main():
    print("-----jwt-----")
    get_token()

    print("-----Basic auth------")
    basic_auth()

    print("-----Basic auth 2------")
    basic_auth2()
    

if __name__ == "__main__":
    main()

 get_token() Results:

{'code': 'SAE-080011',
 'details': {'additionalErrors': [],
             'additionalInfo': {},
             'detailedDescription': '',
             'responseAction': ''},
 'message': 'This session timed out. Refresh and try again.',

basic_auth() Results:

 'message': "We couldn't continue with this authorization key. Enter a new "
            'key, then try again.',
 'type': 'ERROR'}

basic_auth2() Results:

{'code': 'SAE-080002',
 'details': {'additionalErrors': [],
             'additionalInfo': {},
             'detailedDescription': '',
             'responseAction': ''},
 'message': 'Authorisation Header is missing!',
 'type': 'ERROR'}

None of the methods work and the documentation seems to be wrong about sending the credentials via the body since it only seems to care about my authentication header.

To summarize my main questions.
1. Which method is the right one?
2. What am i missing?
3. In the first method the secret key in the jwt.encode(key=?).. Where do i get that from or what is that? Im not familiar with jwt's..
