I am starting an application from my Blazor server side app.
Normally if this application is started manually, there comes a dialog box and I have to press to an “OK” button. After pressing the button the app continues working.

When I start the app from my C# app, the application runs unavoidable in the background and waits again for the confirmation.But there is no interface (dailog box) any more visible.
How can I confirm this dialog box, that is no more visible, programatically in my code?

I have following code for starting the application:

 public void SDB()
 {
    Process_Backup = new Process               
    {
      StartInfo = new ProcessStartInfo
      {
         FileName = app_path,
         Arguments = "",                        
         CreateNoWindow = false
      }
    };
    Process_Backup.Start();   
    //code needed for confirming the hidden dialog box
 }

Update-1:

I have written following Javascript interop code to my host.cshtml of my Blazor server side app, but have problem with bringing the app in the background to foreground:

 public async Task SDB()
 {
    Process_Backup = new Process               
    {
      StartInfo = new ProcessStartInfo
      {
         FileName = app_path,
         Arguments = "",                        
         CreateNoWindow = false
      }
    };
    Process_Backup.Start();   
    await JS.InvokeVoidAsync("simulateKeyPress", "enter");
 }

added code in host.cshtml (injected in my razor page)

  <script>
    window.simulateKeyPress = function (key) {
    window.focus();
    var event = new KeyboardEvent('keydown', { key: key });
    document.dispatchEvent(event);
    };
  </script>
