xThunkable Webviewer do somthing after loading finish

Hello guys!
Am in my Junior Class and have a project for my class and the problem is how do I make web viewer to do something after loading a webpage? And I mean when WebViewer finished loading, do something Pls how do I manipulate this.

I am used to the old thunkable but seems everything changed here in the xthunkable.

If you have access to the website code, you could inject a Thunkable script available on GitHub that will pass a message to the web viewer when the page is fully loaded or at least when all the DOM elements are loaded. That could then trigger a whole Nother workflow.

Ok! How do I get those scripts and work on them.

It worked Bro!
