Research and implement SharePoint data retrieval for new connector

[NicolasLMP]

Why:
As a developer, I need to research and implement SharePoint data retrieval capabilities to establish the foundation for a new SharePoint connector as an additional data source for Isschat.

DoD:

• Research SharePoint API options (Graph API, SharePoint REST API)
• Set up authentication for SharePoint access (OAuth 2.0, service principal)
• Implement basic SharePoint document retrieval functionality
• Test data extraction from SharePoint document libraries
• Handle different file types (Word, PDF, PowerPoint, etc.)
• Add error handling and connection validation
• Document SharePoint API integration approach
• Test with real SharePoint environment

How:

• Research Microsoft Graph API for SharePoint integration
• Set up authentication using existing Azure AD setup
• Create SharePoint client for document retrieval
• Implement file download and content extraction
• Test with various document types and folder structures
• Add proper error handling for API limits and permissions
• Document authentication setup and API usage
• Validate data retrieval works consistently

blocked because : To integrate a SharePoint connector into Isschat, Microsoft requires the creation of a dedicated Azure AD App Registration in order to allow access to SharePoint documents. To authorize this application to read the SharePoint site and its documents, administrator consent is required (which I cannot grant myself).
