Firebase Notifiation Token Transfer Wrong to IOS Current Version Swift WebView - ios

Question

We are trying to send a notification with firebase in an ios project where we use webview and developed with swift, but token transfer with javascript interface does not work in the current ios version. I have reviewed and tried many examples but it is either not responding at all or giving an unusable error. how can i solve this problem?

config.defaultWebpagePreferences = prefs
return WKWebView(
frame: .zero,
configuration: config
)
}

guard let myURL = url else{
return
}
let request = URLRequest(url: myURL)
uiView.load(request)
