I tried use OpenSC to sign a pdf, but I have this message.

wicho@fedora-jtm:~$ opensc-tool -a

wicho@fedora-jtm:~$ opensc-tool -n

is there any GUI app to use smart card reader?

or how to sign pdf documents in Fedora 42 Silverblue?

edit: another question, how to configure distrobox and gnome boxes to use the smartcard?
