The App Store will no longer accept new apps using UIWebView

Hi,

I got the message from Apple when upload my app:
ITMS-90809: Deprecated API Usage - New apps that use UIWebView are no longer accepted. Instead, use WKWebView for improved security and reliability. Learn more (https://developer.apple.com/documentation/uikit/uiwebview).

I didn't use this library directly but the aad_oauth used.

I searched in source code and it seems that we already use WKWebView instead of.
Just one place we can search UIWebView in ios/Classes/FlutterWebviewPlugin.m
line comment 5 // **UIWebView**Delegate

Is it the case, Apple automatic scan this comment line and reject my app?

Untersuche ios/Classes/FlutterWebviewPlugin.m, insbesondere den Kommentar, in dem UIWebViewDelegate erwähnt wird, und prüfe, wie die Abhängigkeit aad_oauth eingebunden ist. Durchsuche die iOS-Quellen und die Abhängigkeitskonfiguration nach UIWebView-Referenzen und ermittle anschließend, ob die gemeldete Ablehnung im App Store durch dieses Plugin verursacht wird und welche Referenz entfernt oder ersetzt werden muss.
