I wrote a Python script(Google_add.py) which creates users in the Google Workspace. However, When it is run, an AttributeError occurred. How do I resolve this Error?

・Google_add.py　(Excerpt）

PATH = '/opt/Google/credentials.json'
CLIENT_SECRETS = '/opt/Google/client_secrets.json'
credentials = None

#If there are credentials
if os.path.exists(PATH):
    credentials = Credentials.from_authorized_user_file(
      path = PATH,
      scopes = SCOPES)

#If there are no (valid) credentials available
if not credentials or not credentials.valid:
    if credentials and credentials.expired and credentials.refresh_token:
      credentials.refresh(Request())
    else:
      FLOW = flow.InstalledAppFlow.from_client_secrets_file(
        client_secrets_file = CLIENT_SECRETS,
        scopes = SCOPES)
      credentials = FLOW.run_console()
    with open(PATH, 'w') as token:
      token.write(credentials.to_json())

・Error Message

File "Google_add.py", line 186, in <module>
main()
File "Google_add.py", line 172, in main
FLOW.run_console()
AttributeError: 'InstalledAppFlow' object has no attribute 'run_console'

I refer the below site when I wrote it.

In the script, I want to authorize using the user account(not service account). And "run_local_server()" method doesn't work because my linux server isn't a web server (doesn't have httpd, nginx and so on).

(I'm sorry if my writing is hard to read.)
