When a user submits their consent preferences, the workflow logs their data, generates a professional HTML thank-you email with Azure OpenAI, and notifies your team via Slack.\n\n### Setup steps\n1. Connect **Google Sheets OAuth2** for data storage\n2. Configure **Azure OpenAI** credentials for email generation\n3. Set up **SMTP** credentials for sending emails\n4. Connect **Slack API** for team notifications\n5. Replace placeholder email addresses and Slack channel\n6. Activate workflow and integrate webhook URL into your consent form"
