FIDO2 auth against SSH server does not work - no touch interaction, window disappears.

I have tried FIDO2 with RDM for ssh connection to one of my servers but it failed. I have created the key pair with pin + touch on my Yubikey 5C Nano. it never tell me to touch it and pin window immedialy disappear when I enter pin and confirm it. I am on macOS 27.0.1. in terminal key pair is working just fine.
