How to make a specific kodi addon follow other nixpkgs branch?

Help
1

I installed kodi like this:

{
  services.xserver.desktopManager.kodi.enable = true;
  services.xserver.desktopManager.kodi.package =
    pkgs.kodi.withPackages (pkgs: with pkgs; [
      jellycon
      youtube
      visualization-matrix
    ]);
}

I want to make only the youtube addon to follow master branch but failed with this code:
(inputs below is from the flake’s specialArgs)

{ inputs, lib, pkgs, ...}:
let
  pkgs-master = import inputs.nixpkgs-master { inherit system; };
in {
  kodi = prev.kodi // {
    packages = prev.kodi.packages // {
      youtube = pkgs-master.kodi.packages.youtube;
    };
  };
}

Only overlaying the whole kodi is working to make youtube addon follow master branch with this code:

{ inputs, lib, pkgs, ...}:
let
  pkgs-master = import inputs.nixpkgs-master { inherit system; };
in {
  kodi = pkgs-master.kodi;
}

How to make specifically only youtube addon to follow master nixpkgs branch but not the entire kodi and other addons?
Thansk!

{ inputs, lib, pkgs, ... }:
let
  youtube-from-master =
    inputs.nixpkgs-master.legacyPackages.${pkgs.stdenv.hostPlatform.system}.kodiPackages.youtube;
in
{
  services.xserver.desktopManager.kodi.enable = true;
  services.xserver.desktopManager.kodi.package = pkgs.kodi.withPackages (
    pkgs: with pkgs; [
      jellycon
      youtube-from-master
      visualization-matrix
    ]
  );
