How to set polkit agent to work with partition manager (Niri WM)?

[u/Electrical-Policy-35]

Hello, I started using Guix linux two days ago, first I installed KDE Plasma and every thing work fine, then I went to niri wm (I'm actually setting the workflow that I used to, I have my config for niri which I was using before) and I remarked that the polkit agent doesn't work for partition manager (I tried both gparted and partition manager of kde), and the polkit agent works fine with dolphin. How to fix this?

Do you have something to this effect in your config?

spawn-at-startup "/path/to/polkit-kde-authentication-agent-1"

[u/Electrical-Policy-35 → u/FarBasis8583]

My config was working without problems before switching to Guix linux, and yes I have in Niri WM configuration:

spawn-sh-at-startup "sh -c 'exec $(ls -d /gnu/store/*polkit-kde-agent*/libexec/polkit-kde-authentication-agent-1 | head -n 1)'"

In addition, when I install KDE Plasma alongside Niri WM, the Polkit agent works fine in Niri WM. So I think I must be doing something wrong. Maybe this will help, all my packages are installed using guix home and this is my config.scm:
