Web UI (HTML/CSS/JS Interface Widgets)

Hello !
We are working on a project where we use the WebUI plugin for developing the user interface with React. We are currently facing some problems and it would be nice to be able to debug our app. It’s running perfectly in Chromium but when loaded in Unreal with WebUI its not working as intended.

As far as I understand, WebUI is using the internal Chromium Embedded Framework in UE4, which should have a debugger tool that can be opened on localhost: port.

Is it possible with WebUI to open the devTools? And if so, how do we know which port it’s using?

Thanks in advance!
