CLI arguments are not processed in conftest.py in my pytest - python-3.x

Question

My project implementation is to capture details from CLI to determine the environment, to generate the token in that environment and to return the token and the application URL.
Here is the code in conftest.py file
def pytest_addoption(parser):
parser.addoption('--env',
dest='testenv',
choices=["qa","aws","prod"],
default='qa',
help='Specify environment: "qa", "aws", "prod".')
#pytest.fixture(scope='session')
#def conftest_setup(request):
# env = request.config.getoption("--env")
def conftest_setup(request):
env = request.config.getoption("--env")
print(env)
if (env =='aws'):
url='AWSURL'
elif ( env =='prod'):
url='prodURL'
else:
url='QAURL'
token = requests.post(auth=HTTPBasicAuth(clientID, secret),headers=tokenheaders, data=payload)
auth = token.json()['access_token']
return auth,url
test_service.py has
auth1=''
url1=''
def initialCall(conftest_setup):
auth1=conftest_setup[1] # Pretty sure this is wrong, but couldnt get a way to retrieve this
url1=conftest_setup[2]
# Now I want to use the auth1 and url1 obtained from above method to the below method
def response():
print("auth is " ,auth1)
print("URL is " ,url1)
headers = {'content-type': 'application/json',
'Authorization' : auth1}
response=
(requests.post(url1,data=json.dumps(data1),headers=headers)).json()
Currently, I get this exception
request = <FixtureRequest for <Function
> ???

No console output observed for print(env) in conftest.py file while
auth is None
URL IS None
are observed for print statements in test_service
CLI execution throws error when I pass pytest -s --env='qa' but is acceptable for pytest -s --env=qa. So the CLI arguments are captured.
Please help me to capture the auth and url from conftest.py across the test file.
Also, is there a way I can use this auth,url returned from conftest.py to use across multiple test files?

Many thanks to #hoefling for providing valuable insights.
I've added/updated the fixture in the following places and declared auth1 and url1 as global inside initialcall method. It now works as expected.
test_service.py has
#pytest.fixture(autouse=True, scope='session')
def initialCall(conftest_setup):
global auth1,AN_API1
auth1 = conftest_setup[0]
AN_API1=conftest_setup[1]
conftest.py has
#pytest.fixture(autouse=True,scope='session')
def conftest_setup(request):
