How can I use the QT/KDE File picker on nixOS, i3wm? - Lemmy.world

What I’ve done is installing xdg-desktop-portal libsForQt5.xdg-desktop-portal-kde libsForQt5.kdialog and adding xdg.portal.enable = true; xdg.portal.extraPortals = [ pkgs.libsForQt5.xdg-desktop-portal-kde ]; environment.sessionVariables.XDG_CURRENT_DESKTOP = "kde"; to my configuration.nix, but while I do get the qt file picker on my web browser, the theming is broken and it looks like this [https://lemmy.world/pictrs/image/47a20991-162f-47f1-a465-be7e01973e05.png]
