Yubikey is not working


currently I try to switch from Ubuntu to OpenSUSE because I like the Rolling-Release idea. Currently many things are working fine but I am not able to get my yubikey TOTP to work on my usb port. I am able to install the flat paket but I always see a message that I need to install the pcsc.

I followed the following website but I am not able to get yubikey app with flatpak working.

Does anyone have a manual or an hint how I it up and running ?
