Pull request overview

This PR fixes a critical logic error in the PowerShell token acquisition script documentation and enhances error handling throughout. The main issue addressed is that the script would continue executing even when the connector module installation failed, leading to runtime errors.

Key Changes

• Critical logic fix: Wrapped the main script logic (lines 87-161) inside the module existence check to prevent execution when installation fails
• Improved process execution: Added -Wait parameter to Start-Process calls to ensure installers complete before continuing
• Enhanced error handling: Added existence checks and -ErrorAction SilentlyContinue for cleanup operations to prevent failures during cleanup
