QT Theme using HM and Icon Theme names

Help
1

I’m trying to have a universal theme for my desktop (Catppuccin Mocha Pink), but I’m running into issues setting any qt theme.

{
  qt = {
    enable = true;
    style = {
      package = pkgs.adwaita-qt;
      name = "adwaita-dark";
    };
  };

I added this to my HM-Config, but QT Applications (Dolphin) are just white.
When using

{
  qt = {
    enable = true;
    platformTheme = "gtk";
  };
}

the borders of Dolphin look fine, but the background is still white.
I tried using qt5ct (QT_QPA_PLATFORMTHEME = "qt5ct";), but I had the same issue, the only way to get a dark background was to use kvantum with one of the default themes.

Additionally, I have trouble determining the naming of themes inside packages, for example I would like to use iconTheme.package.pkgs.catppuccin-papirus-folders with a pink accent, but I am not certain what to set iconTheme.name to.

I’m on unstable with Hyprland.
