about "Sign In With Apple" error handling (Sign In With Apple JS)

I implement "Sign In With Apple".

After having carried out AppleID.auth.signIn(), I can't error handling when touch id or face id starts and pushed the cancel button.

I cannot cancel the Loading indication in the "Sign In With Apple" button.

usePopup: true

↓

//Listen for authorization failures
document.addEventListener('AppleIDSignInOnFailure', (error) => {
     //handle error.
});

error handling is possible here, but certification UI does not come out with an actual machine of iPhone.

usePopup: false is there the method that can handle an error in this?

It would be greatly appreciated if you could explain the details.
