Output PowerShell Runspace Function to WPF textbox - wpf

Question

I am having trouble getting my "sync-folder" function to output to the textbox as it runs. I have tried looking over a lot of guides around the net including searching here and I'm not able to figure it out. I am hoping someone who understands this better than me can show me how to do it in my test example below:
$Global:syncHash = [hashtable]::Synchronized(#{})
$newRunspace =[runspacefactory]::CreateRunspace()
$newRunspace.ApartmentState = "STA"
$newRunspace.ThreadOptions = "ReuseThread"
$newRunspace.Open()
$newRunspace.SessionStateProxy.SetVariable("syncHash",$syncHash)
