Outlook Powershell Script - powershell

Question

I have been doing some digging and trying to find a way to remove a PST from Outlook with a script. I don't entirely know how to script but am trying to learn. I found this old Stackoverflow but I am unsure how to actually enter the information I need into it.
How to disconnect PST file from Outlook using Powershell?
The script in question is below.
$Outlook = new-object -com outlook.application
$Namespace = $Outlook.getNamespace("MAPI")
$PSTtoDelete = "c:\test\pst.pst"
$PST = $namespace.Stores | ? {$_.FilePath -eq $PSTtoDelete}
$PSTRoot = $PST.GetRootFolder()
$PSTFolder = $namespace.Folders.Item($PSTRoot.Name)
$namespace.GetType().InvokeMember('RemoveStore',[System.Reflection.BindingFlags]::InvokeMethod,$null,$namespace,($PSTFolder))
I understand the third line, where to enter the file path to the PST itself but I am not sure what to enter for the rest of the lines.
I know this is a total newbie question, but any help would be super appreciated.
Thank you!

Here is a function i just wrote hope it helps
function Remove-OutlookStore($StoreFilePath){
get-process | where { $_.Name -like "Outlook" }| kill
$Outlook = new-object -com outlook.application
$Namespace = $Outlook.GetNamespace("mapi")
$Store = $namespace.Stores | ?{$_.FilePath -like $StoreFilePath} | %{$_}
$namespace.RemoveStore($Store.GetRootFolder())
get-process | where { $_.Name -like "Outlook" }| kill
}
Remove-OutlookStore -StoreFilePath C:\Test\Test.pst
