Adding member to a Google group using Google API

Question

I'm trying to add email ids to a Google group using google APIs and Python3. I need help, figuring out what scopes it needs since I am getting the error: Request is missing required authentication credential. Expected OAuth 2 access token, login cookie or other valid authentication credential.

My code:

from __future__ import print_function

import os.path

from google.auth.transport.requests import Request
from google.oauth2.credentials import Credentials
from google_auth_oauthlib.flow import InstalledAppFlow
from googleapiclient.discovery import build

# If modifying these scopes, delete the file token.json.
SCOPES = ['https://www.googleapis.com/auth/admin.directory.user']


def main():
    """Shows basic usage of the Admin SDK Directory API.
    Prints the emails and names of the first 10 users in the domain.
    """
    creds = None
    # The file token.json stores the user's access and refresh tokens, and is
    # created automatically when the authorization flow completes for the first
    # time.
    if os.path.exists('token.json'):
        creds = Credentials.from_authorized_user_file('token.json', SCOPES)
        print(creds)
    # If there are no (valid) credentials available, let the user log in.
    if not creds or not creds.valid:
        if creds and creds.expired and creds.refresh_token:
            creds.refresh(Request())
        else:
            flow = InstalledAppFlow.from_client_secrets_file(
                'client_secrets.json', SCOPES)
            creds = flow.run_local_server(port=0)
        # Save the credentials for the next run
        with open('token.json', 'w') as token:
            token.write(creds.to_json())

    service = build('admin', 'directory_v1', credentials=creds)
    group_result = service.groups().insert(body={
                         'groupKey': '[email protected]', # group key
                         'email': '[email protected]' # user email who need to insert in google groups
                      }).execute() 
    print(group_result)

Anyone please help me with the issue.

You can always check the docs for each method to see what scope it requires. In your case groups.insert requires one of the following scopes.
