How to implement refres token to youtube API

I want to upload a video with youtube API and always I get a message from google to terminal check this link to validate your application I read that I can use for it a refresh token function I found some on the internet but it is not working. I do not know why but I have done all steps before this so for every help I will be happy. Thanks

function:

import pickleimport osfrom google_auth_oauthlib.flow import Flow, InstalledAppFlowfrom googleapiclient.discovery import buildfrom googleapiclient.http import MediaFileUpload, MediaIoBaseDownloadfrom google.auth.transport.requests import Requestimport datetimedef Create_Service(client_secret_file, api_name, api_version, *scopes):    print(client_secret_file, api_name, api_version, scopes, sep='-')    CLIENT_SECRET_FILE = client_secret_file    API_SERVICE_NAME = api_name    API_VERSION = api_version    SCOPES = [scope for scope in scopes[0]]    print(SCOPES)    cred = None    pickle_file = f'token_{API_SERVICE_NAME}_{API_VERSION}.pickle'    # print(pickle_file)    if os.path.exists(pickle_file):        with open(pickle_file, 'rb') as token:            cred = pickle.load(token)    if not cred or not cred.valid:        if cred and cred.expired and cred.refresh_token:            cred.refresh(Request())        else:            flow = InstalledAppFlow.from_client_secrets_file(CLIENT_SECRET_FILE, SCOPES)            cred = flow.run_console()        with open(pickle_file, 'wb') as token:            pickle.dump(cred, token)    try:        service = build(API_SERVICE_NAME, API_VERSION, credentials=cred)        print(API_SERVICE_NAME, 'service created successfully')        return service    except Exception as e:        print('Unable to connect.')        print(e)        return Nonedef convert_to_RFC_datetime(year=1900, month=1, day=1, hour=0, minute=0):    dt = datetime.datetime(year, month, day, hour, minute, 0).isoformat() +'Z'    return dt

and this is my code:
