Execute Powershell cmdlet that have user prompts within C# WPF application

I am attempting to create a WPF application that will execute some powershell commands using a 3rd party module (ShareGate). After extensive research and banging my head on the keyboard, I have gotten the application to at least execute the cmdlets I have asked for. The cmdlet in question, if run in powershell, will prompt the user to log into a web service using edge I believe. When running the cmdlet from the application, it throws an error which is misleading "during the last update edge was not able to be installed...."

I think that this error is coming up because this implementation isn't allowing powershell to pop open the browser like it does within a powershell window.

My question is this: "How can I redirect the user prompt to come up within the wpf application? or can I?"

here is my method:

        public Task StartSGMigrations(IProgress<string> progress)
        {
            var sharegatePath = Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData) + "\\Apps\\ShareGate\\Sharegate.Automation.dll";
            if (client != null)
            {
                try
                {
                    InitialSessionState iss = InitialSessionState.CreateDefault();
                    iss.ImportPSModule(new string[] { sharegatePath });
                    using (Runspace myRunSpace = RunspaceFactory.CreateRunspace(iss))
                    {
                        myRunSpace.Open();
                        using (PowerShell powershell = PowerShell.Create())
                        {
                            Dictionary<string, string> parameters = new Dictionary<string, string>();
                            powershell.AddScript("New-CopySettings -OnContentItemExists IncrementalUpdate");
                            powershell.AddScript("Connect-box -email " + _admin + " -admin");
                            powershell.AddScript("Connect-Site -Url \"https://xxxx-admin.sharepoint.com\" -Browser");

                            powershell.Runspace = myRunSpace;
                            var results = powershell.Invoke();
                            var errors = myRunSpace.SessionStateProxy.PSVariable.GetValue("Error");

                            foreach (var result in results)
                            {
                                progress.Report(result.ToString() + Environment.NewLine);
                            }
                        }
                        myRunSpace.Close();
                    }
                }
                catch (Exception ex)
                {
                    progress.Report(ex.Message);
                }
            }
            else
            {
                progress.Report("not connected to Box");
            }

            return Task.CompletedTask;
        }
    }
