Merge Metadata and Base64 Code\n5. Code Node to write the Keywords into the Metadata (dc:subject)\n6. Convert to file and update the original file in the Google Drive folder\n\n## The following accesses are required for the workflow:\n- Google Drive: [Documentation]({{ $env.WEBHOOK_URL }}\n- AI API access (e.g. via OpenAI, Anthropic, Google or Ollama)\n\nYou can contact me via LinkedIn, if you have any questions: {{ $env.WEBHOOK_URL }}"
