Step 4: Use Your OAuth2 Credentials

You can now use your OAuth2 credentials to authenticate with Google Cloud services. For example, you can use the google-auth-library library in Python to authenticate:

import os
from google.oauth2 import service_account

# Load your private key file
credentials = service_account.Credentials.from_service_account_file(
    '<private-key-file>',
    scopes=['https://www.googleapis.com/auth/cloud-platform']
)

# Use the credentials to make API requests
client = googleapiclient.discovery.build('cloudresourcemanager', 'v1', credentials=credentials)

Remember to replace <service-account-name>, <private-key-file>, and <service-account-email> with your actual values.
