C#, .NET, How can I make a code generator download when my NuGet package is installed?

csproj, Engine: <Project Sdk="Microsoft.NET.Sdk">

<PropertyGroup>

<TargetFramework>net8.0</TargetFramework>

<ImplicitUsings>enable</ImplicitUsings>

<Nullable>enable</Nullable>

<GeneratePackageOnBuild>True</GeneratePackageOnBuild>

Target: When someone downloads my Engine.dll library through NuGet, for example: <ItemGroup><PackageReference Include="Engine" Version="1.1.0"/></ItemGroup>a code generator should be downloaded that takes care of creating the entry point with a couple of modifications: context.RegisterSourceOutput(context.CompilationProvider, (ctx, compilation) =>{var programSource = @"using Engine;using System;public static class Program{public static void Main(string[] args){EngineInitializer.Initialize();}}";ctx.AddSource("Program.g.cs", SourceText.From(programSource, Encoding.UTF8));});but I want to avoid having the developer install the 2 packages separately. Is it possible to achieve this?
