❔ How can I create a command handler factory, with this structure that I have

// Comand Handler interface
public interface ICommandHandler<in T> where T : ICommand
{
    Task<CommandResult> Execute(T command);
}

// Command Interface
public interface ICommand
{
    public string MyProperty { get; set; }

}

// MyCommand class
public class MyCommand : ICommand
{
    public public string MyProperty { get; set; }
}

// MyCommand handle
public class MyCommandHandler : ICommandHandler<MyCommand>
{
    public async Task<CommandResult> Execute(MyCommand command)
    {
     
    }
}

// Command Factory
public class CommandHandlerFactory
{
    private readonly ICommandHandler<MyCommand> _myCommand;

    public CommandHandlerFactory(ICommandHandler<MyCommand> myCommand)
    {
        _myCommand = myCommand;
    }

    public ICommandHandler<?> Build(MyEnum myEnum)
    {
        var builder = new Dictionary<MyEnum, ICommandHandler<?>>
        {
            { LineOfBusiMyEnumessEnum.MyEnumValue, _myCommand }
        };
        return builder[myEnum];
    }
}

// Comand Handler interface
public interface ICommandHandler<in T> where T : ICommand
{
    Task<CommandResult> Execute(T command);
}

// Command Interface
public interface ICommand
{
    public string MyProperty { get; set; }

}

// MyCommand class
public class MyCommand : ICommand
{
    public public string MyProperty { get; set; }
}

// MyCommand handle
public class MyCommandHandler : ICommandHandler<MyCommand>
{
    public async Task<CommandResult> Execute(MyCommand command)
    {
     
    }
}

// Command Factory
public class CommandHandlerFactory
{
    private readonly ICommandHandler<MyCommand> _myCommand;

    public CommandHandlerFactory(ICommandHandler<MyCommand> myCommand)
    {
        _myCommand = myCommand;
    }

    public ICommandHandler<?> Build(MyEnum myEnum)
    {
        var builder = new Dictionary<MyEnum, ICommandHandler<?>>
        {
            { LineOfBusiMyEnumessEnum.MyEnumValue, _myCommand }
        };
        return builder[myEnum];
    }
}
