List Item changelog through Powershell (CSOM)

Question

Hi!
I am trying to figure out how to get information about the historical changes made to a sharepoint list.
So far, I have come up with the below code. My goal is to get details like - the type of change, time, new value, old value, row/column names and modified by. I know this has something to do with Microsoft.Sharepoint.Client.Change but can't figure out the
logic behind it.
[Reflection.Assembly]::LoadFrom("$scriptdir\Microsoft.SharePoint.Client.dll")
$context = New-Object Microsoft.SharePoint.Client.ClientContext($siteURL)
$context.RequestTimeOut = 1000 * 60 * 10;
$context.AuthenticationMode = [Microsoft.SharePoint.Client.ClientAuthenticationMode]::Default
$securePassword = ConvertTo-SecureString $password -AsPlainText -Force
$credentials = New-Object Microsoft.SharePoint.Client.SharePointOnlineCredentials($username, $securePassword)
$context.Credentials = $credentials
$web = $context.Web
$site = $context.Site
$context.Load($web)
$context.Load($site)
$context.ExecuteQuery()
Set-Variable -Name "clientContext" -Value $context -Scope Global
Set-Variable -Name "rootSiteUrl" -Value $siteURL -Scope Global
Function Get-ListChanges {
$listName = "Tasks"
$list = $clientContext.Web.Lists.GetByTitle($listName)
$cq = new-object Microsoft.Sharepoint.Client.ChangeQuery($true,$true)
$changes = $list.GetChanges($cq)
$clientContext.Load($changes)
$clientContext.ExecuteQuery()
$changes.count
foreach ($item in $changes) {
# get data here from specific column name/old values/newvalues
Any help would be appreciated. Thank you for looking in to this.

Hi A Tank,
You need to call the properties of change object inside that foreach loop like this:
foreach ($item in $changes) {
# get data here from specific column name/old values/newvalues
Write-Host $item.ChangeType '--' $item.Time
All the properties are listed here:
