How to run MSTest with WinAppDriver from C# code?

Question

I am able to execute MSTest with WinAppDriver from a command line with

mstest /testcontainer:C:\Users\...\dev\WinAppDriver\Samples\C#\AlarmClockTest\bin\Debug\AlarmClockTest.dll

Now I have to do the same from another UWP application. I am attempting to do it with Process class. My code:

string filename = @"C:\Users\...\dev\WinAppDriver\Samples\C#\AlarmClockTest\bin\Debug\AlarmClockTest.dll";

try
{
    using (Process process = new Process())
    {
        process.StartInfo.Verb = "runas";
        process.StartInfo.FileName = "CMD.exe";
        process.StartInfo.Arguments = "mstest /testcontainer:" + filename;
        process.StartInfo.UseShellExecute = false;
        _ = process.Start();
    }
}
catch (Exception ex)
{
    Console.WriteLine(ex.Message);
}

When I am executing this code, I am getting cmd prompt opened at my UWP project's directory's bin/x86/Debug/projectname directory. The command to trigger a test had not been executed. I got same results when I replaced an argument with @ECHO OFF ECHO Hello World!.
