Which nixpkgs version are you running. If it is stable this is probably due to plasmusic-toolbar and application-title-bar not being available there yet.

[HeitorAugustoLN]

It is probably due to these packages being available currently only in nixos-unstable. But if you want to use it, you can add them as custom packages in your nixos configuration or get them from nixos-unstable using an overlay. I can help you with that if you need.

I can access unstable packages with pkgs.unstable, but don't know how to pass it to plasma-manager

If your flake have an nixos-unstable input, you could make the nixpkgs from plasma-manager follow it

[HeitorAugustoLN]

Like this:

inputs = {
  nixpkgs.url = "github:NixOS/nixpkgs/nixos-24.05";
  nixpkgs-unstable.url = "github:NixOS/nixpkgs/nixos-unstable";
  home-manager = {
    url = "github:nix-community/home-manager";
    inputs.nixpkgs.follows = "nixpkgs";
  };
  plasma-manager = {
    url = "github:nix-community/plasma-manager";
    inputs.nixpkgs.follows = "nixpkgs-unstable";
    inputs.home-manager.follows = "home-manager";
  };
};

I didn't test, but it should work
