Passkey cancel event in Safari is identified as “Passkey not supported”

[chpapa]

Describe the bug
When I tried to cancel the Passkey login on Safari, iOS 17.5.1; It shows the following error:

Passkey is not supported in your browser. Please select another authentication method.

It seems not appropriate. Yet:

1. I haven’t verified on other browsers
2. Not sure is it the limitation of Passkey/WebAuthn, is it possible to distinguish between Passkey not supported / Passkey cancelled?

Authgear Version
SaaS

Expected behavior
Give different error messages between Passkey not supported in browser, vs Passkey cancelled.
