Get software center updates install status from sccm client using powershell

Question

I want to get the real time status of all patches currently in the SCCM Client Software center. I've attempted to use multiple scripts I've found online but none of them end up showing me real time results. I can get all the currently available updates and well as their corresponding software update groups that are deploying those missing patches but have not yet discovered how to link the missing patches to their current status like Software Center currently does.

The function below currently works and is what I use to install the missing patches.

Function Install-SCCMPatchesAvailable {
  [CmdletBinding()]
  param(
    [Parameter(
      Position = 0,
      Mandatory = $false,
      ValueFromPipelineByPropertyName = $true,
      HelpMessage = "Do not reboot server after patches install")]
    [ValidateNotNullOrEmpty()]
    [switch]
    $DoNotReboot
  )

  begin {
    Write-Verbose "Install-SCCMPatchesAvailable: Started"
  }

  process {
    try {
      ([wmiclass]'ROOT\ccm\ClientSDK:CCM_SoftwareUpdatesManager').InstallUpdates([System.Management.ManagementObject[]] `
        (Get-WmiObject -Query 'SELECT * FROM CCM_SoftwareUpdate' -namespace 'ROOT\ccm\ClientSDK'))

      while (-not((Get-WmiObject -Namespace 'ROOT\ccm\ClientSDK' -Class 'CCM_ClientUtilities' -list).DetermineIfRebootPending().RebootPending)) {
        $Time = (get-date).ToShortTimeString()
        Write-Output "Still Patching @ $Time"
        Start-Sleep -s 60
      }
      if (-not $PSBoundParameters.ContainsKey('DoNotReboot')) {
        if ((Get-WmiObject -Namespace 'ROOT\ccm\ClientSDK' -Class 'CCM_ClientUtilities' -list).DetermineIfRebootPending().RebootPending) {
          (Get-WmiObject -Namespace 'ROOT\ccm\ClientSDK' -Class 'CCM_ClientUtilities' -list).RestartComputer()
        }
      }
    }
    catch {
      Write-Error -Message "Something went wrong with Install-SCCMPatchesAvailable.`n`nError.Exception.Message : $($_.Exception.Message)`nError.Exception.FullName: $($_.Exception.GetType().FullName)"
    }
  }

  end {
    Write-Verbose "Install-SCCMPatchesAvailable: Completed"
  }
} #End Install-SCCMPatchesAvailable

I would like to replace:

$Time = (get-date).ToShortTimeString()
Write-Output "Still Patching @ $Time"
Start-Sleep -s 60

With something showing the patches listed in the sccm software center and their corresponding patch status (Downloading, installing, pending verification, needs reboot, etc...), which the software center shows using its GUI interface.

I can also view any missing updates using a module I wrote that returns one or more missing patches objects. However, the Status for the object can only show Missing or Installed . Not the actual SCCM status of the patch. Example:

Software Centre displays progress for software installs and advertisements. It does not show patch status other than Installed/Missing, so I suspect if you want to enumerate the progress status for that patch, you'll need to scrape logs to determine if the client is doing anything with each respective patch to create a calculated status message at runtime.
