// and from https://ai.google.dev/gemini-api/docs/quickstart?hl=de for using Gemini API
// Before using, make sure to export the Google Gemini API key as an environment variable:
//  export GOOGLE_API_KEY="your_api_key_here"
//  Keys can be obtained from https://aistudio.google.com/app/api-keys
//  Also make sure to install the package via sudo npm install @google/genai
