I have configured a login flow similar to the flow shown in Creating a password-less browser login flow. The only difference is that I don't want to use OTP, but just want to allow using either a password or passwordless WebAuthn, so instead of "Password with OTP" I just have the password form.
The problem is that in this setup a user having passwordless authentication configured can never enter a password as an alternative anymore (e.g., when logging in on another device).
The screen that appears after entering the username just shows "Sign in with Security Key". Contrary to the documentation linked above, there is no "Try another way" link.
