Would be helpful if you could explain the code more properly

Hello Everyone,
I have developed a JavaFx application which has a WebView component for logging in to the application which I want to automate. I'd used an existing solution where I had to call WebViewObject.getEngine().executeScript() and manually add the username and password from the HTML Class tags of the login page and then hit the login button, but this would never happen in sequential order, meaning the compiler always used to hit login button first and then the tried the enter username and password, which is definitely wrong.
Hence, Selenium popped up in my head and I just Googled it since I'm pretty much new to it and found this repository. I'll list some of my doubts and it would be helpful if anybody could help me.

1. I want to automate the logging process which is WebView
2. How would I make my existing project interact with this code?
