Distinguish between when the user declined the "Sign In" prompt or cancelled the flow in iOS

The issue https://github.com/FormidableLabs/react-native-app-auth/issues/565 suggests a way to differentiate between cancels from login failures.

But in iOS there are two types of cancellations in general:

1. when the user presses "Cancel" on the prompt, that is by declining to sign in itself which is before the browser flow is even started
2. when the user actually cancels the login flow or closes the browser

Is there anyway to distinguish between these two cases for iOS? For proper tracking purposes, I'd like to know when the user declines the prompt specifically.

Currently if you check the error as per suggested in here, both of these cases resolve to user cancellation which is based on this -3 error code.

まず issue 565 のキャンセルに関する議論と、参照されている AppAuth-iOS Source/AppAuthCore/OIDError.h のエラーコードを確認します。2 つの iOS のキャンセル経路が React Native bridge を通じて異なるシグナルを公開しているかを判断します。完了条件は、呼び出し側が Sign In プロンプトの拒否と、ブラウザフローのキャンセルまたは終了を確実に区別できることです。
