Has anyone got actual Passkeys working?

Hi,
I've been using Passkeys for my Miniflux instance for quite some time. I've generated two: one on Android, one on a Chromebook.
I can log in with both of them. However, I need to enter my username first and then click on "Login with Passkey".

With yesterday's release (v2.2.2), an explanation was added for Passkey login:

"Please enter your username if you're using a security key. This is not required if you are using a Passkey (discoverable credentials)."

This made me wonder if my Passkeys are not really considered actual Passkeys but act like security keys in this context.
When generating a Passkey as intended via the Miniflux web interface, the browser is prompting me to "create a Passkey", which sounds correct. However, I noticed that the Miniflux Passkeys don't show up in Chrome's Password Manager, whereas other Passkeys, e.g. for Github or Amazon do.
That made me wonder if people have actual Passkeys synced and working for Miniflux.

(This is on Chrome v130 and v129)
