New apps that uses UIWebView are no longer accepted instead use WKWebView

Hello,
In my game i have a button that opens a URL, when doing that with Application.url() Apple did not accept it and told me to use SFSafariViewController.
After searching the web i found this tutorial
https://titanwolf.org/Network/Articles/Article?AID=87970270-d9bf-47c1-bd8f-0367a049a77b#gsc.tab=0

I implemented it in my code and uploaded it to the app connect using Xcode, now I am getting this message when uploading - (“ITMS-90809: Deprecated API Usage - existing app that use UIWebView are no longer accepted”)

I don’t Really understand about this plugins and libraries because i have never dealt with it, how do i replace it to be as apple wants?
My code i practically the same as in the tutorial.

Contact your app reviewer and tell them that they are wrong. Games are allowed to use Application.OpenURL

I don’t understand what they want from me,
I implemented SFSafariViewController but they still say that the site is opened with safari and tell me to use SFSafariViewController and rejecting my game, has anyone encountered that from Apple? what should i do.
