Gnome Papers, some deps to digitally sign missed

Hello Nix-ers, It seems that GNOME’s new PDF viewer has a digital PDF signature feature (PADES), which is very handy in countries where public digital signatures are becoming widespread. However, it doesn’t seem to work on NixOS due to some missing dependencies. So far, I’ve found p11-kit, nettle, and sssd (for pam_sss) all already in nixpkgs. Does anyone have any ideas on how to report this issue? These are lightweight dependencies, so since the signature feature is present by default, I imagine they should be included and not just available as an optional add-on.

The package itself document maintainers with mail and github handles, though I’m not sure if there is a more proper way to reach out:
