Can I review the extension source?

Yes, you can inspect the extension’s configuration by opening the .trex file in any text editor (like Notepad or VS Code).

This file includes:

  • The extension’s hosted URL

  • Author and support contact details

  • Whether the extension requests full data access

  • References to external JavaScript libraries or resources

🔍 Reviewing the .trex file is a great way to verify the source and behavior of the extension before deployment.
