OAuth on Web works but on iOS app's webview gives a security policy error

API Endpoint(s) and/or Zoom API Event(s)
There is no specific endpoint that is giving the issue. It is primarily a bug with Zoom website login inside an iOS or Android app’s webview.

I have a flutter app that is working on the web for integration with Zoom. When I try to login to authenticate for Zoom via the web version of the app, it works seamlessly: Imgur: The magic of the Internet

However when I try to login to authenticate for Zoom via the webview inside the app (in an iOS device for example), I get this weird error: Imgur: The magic of the Internet

The error message gave this code: 1453805595095095755

Any idea how to bypass this issue? I am using standard flutter webview btw.

My code is as follows:

          initialUrl: url,
          userAgent: 'random',
          javascriptMode: JavascriptMode.unrestricted,
          onPageStarted: (url) {},

Hey so I don’t know why exactly Zoom doesn’t work in iOS or Android webviews made by the traditional Flutter webview (by official Flutter team) but I figured out a workaround to make it work using the Flutter In-App Webview library: flutter_inappwebview | Flutter Package. Hope this helps others who may get this issue by trying to use the plain-vanilla Flutter webviews to do oAuth logins with Zoom.
