Create test users using MS Graph API from list or ask ChatGPT to generate test users

Summary

Create test users using MS Graph API from list or ask ChatGPT to generate test users. This script uses the ChatGPT model from OpenAI to generate a list of users. The script can also use a list of users that you provide.

Pre-requisites

• Microsoft.Graph.Sites PowerShell module
• An Open AI API key which can be done by creating an account for using Open AI API
  • Once the key is obatined, set the value of $openai_api_key in the script with that key

• Microsoft Graph PowerShell
