Problem : run console application exe having confirm prompt (using powershell script in background)

I am trying to run a console application in background using powershell script and in the main method of "program.cs" it requires user confirmation. Working of this console application is to update some configurations and settings before i install a main application.

ConsoleApp.exe -> below is sample code from my "Program.cs"

public class Program
{
    static void Main(string[] args)
    {
        RunCommandLine();
    }

    public static void RunCommandLine()
    {
        Console.WriteLine("Do you wan to continue (Yes/No)?");
        var response = Console.ReadKey();
        if (response.Key.ToString().StartsWith("y"))
        {
            //Some code here
            Console.WriteLine("Working with - Yes");
        }
        Console.WriteLine();
        //Some code here
        Console.WriteLine("Working without -Yes");
        Console.ReadLine();

    }
}

What I have tried:

Following command is working fine when I am not running this "ConsoleApp.exe" in background

Start-Process "c:\temp\ConsoleApp.exe"
$wshell = New-Object -ComObject wscript.shell;
$wshell.AppActivate('ConsoleApp')
$wshell.SendKeys('y')

But it stop working when i run it in background using following command

Start-Process -NoNewWindow "c:\temp\ConsoleApp.exe"

possible reason is when running it in background, there is no interactive window to send keystrokes.

I have tried some other powershell commands as well like

C:\Temp\ConsoleApp.exe -Confirm:$false
 echo Y | C:\Temp\ConsoleApp.exe
 Write-Output Y | C:\Temp\ConsoleApp.exe

Is there any other way to achieve the same?
