Good

A button in fuse, could I run a function inside a webview? Maybe with EvaluateJS ?

Or inject code, after pressing a button?

Thank you

Thank you, I have a question. I can enter javascript code, just when I create the webview, but I do not know how to interact with the web later.

That is to say. After pressing a button (UI Control) as you could inject code or execute a function inside a webview already created.

I do not know where to start.
