unable to use the FailOverClusters module in a .ps1 file when calling the file from c#

Error when trying to call a .ps1 file from c# the "FailoverClusters" module is not available. I am trying to provide some self service administration to people via a web page and the first step in that is getting c# to call a .ps1 file using the Get-Cluster command. It appears that when I call the .ps1 from c# most of the modules are available in that run space but the "FailoverClusters" is not. When I create just a test file to run this command from the c# call, it returns nothing.

get-module -ListAvailable | Where-Object {$_.Name -like "*clust*"}

However when I run the above code in the powershell console as me, I see the module name "FailoverClusters".

I don't know what c# is running under, but whatever user it is running under (assumed me since I am clicking the debug button), does not appear to have access to the FailOverClusters module or commands.

See code....

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Management.Automation;
using System.Management.Automation.Runspaces;
using Microsoft.FailoverClusters.PowerShell;

PowerShell posh = PowerShell.Create();
            posh.AddCommand(@"C:\test\Test.ps1");
           
            var results = posh.Invoke();
            Console.Out.WriteLine("Done");
            foreach (var result in results)
            {
                Console.Out.WriteLine(result.BaseObject.ToString());
            }
            Console.Out.WriteLine("Done");
            Console.In.ReadLine();
