I am following the instructions here https://developer.apple.com/documentation/signinwithapplejs/configuring_your_webpage_for_sign_in_with_apple
When I use `response_mode=web_message` I cannot see the events being fired.
I can see `AppleIDSignInOnFailure` being fired when I close the window (using the browsers 'X' button). I cannot see either `AppleIDSignInOnSuccess` or `AppleIDSignInOnFailure` fired when clicking `Cancel` or `Continue` on the pop-up.
I am using Chrome for this testing.
Is `usePopup` / `response_mode=web_message` ready for production use ?
