App runs, but nothing happens

[Rotciv18]

Hello! I am trying to run this project as one of my twitch extensions for learning, but I can't quite make it functional at all~

Here are my steps:
• Cloned the project
• Created an extension at twitch console
• Added a new project with Developer Rig with the created extension, using the bot-commander as the source
• Installed the extension in my twitch channel
• Clicked "Run Front-end" at Developer Rig
The application runs without errors, but the extension doesn't work at all.

I also made sure the base URI from the extension was localhost:8080 at twitch console. Am I missing something...? I also can't see any View at the Dev Rig.
OS: Windows

Thank you so much for your support
