CR: Need a way to detect "cancel"

[hemanth]

Proposed Change

Need a way to programmatically detect when the user has cancelled the "Use passkey from another device" browser native prompt by clicking the "Cancel" button. This could be achieved by adding a new property or event to the prompt that indicates whether the user has cancelled the prompt.

^ the "cancel" button there.

Use passkey from another device" browser native prompt by clicking the "Cancel" button.

This prompt is WebAuthn client-specific.

If the user cancels out of a WebAuthn ceremony, NotAllowedError is returned.

Also, take a look at #2095 which is planned for Level 4.

NotAllowedError can also be returned synchronously without user interaction?

This is essentially a duplicate of #2095. Please feel free to chime in there, or subscribe for updates.
