CSOM powershell to update search navigation sharepoint 2013

Question

I am wanting to write some client side powershell to update the search navigation on global search. I have found many examples of this with server side but none using client side. anyone with any ideas?

Add-Type -Path 'C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\15\ISAPI\Microsoft.SharePoint.Client.dll'
Add-Type -Path 'C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\15\ISAPI\Microsoft.SharePoint.Client.Runtime.dll'
Add-Type -Path 'C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\15\ISAPI\Microsoft.SharePoint.Client.Publishing.dll'
Add-Type -Path 'C:\Program Files\Common Files\Microsoft Shared\Web ServerExtensions\15\ISAPI\Microsoft.SharePoint.Client.Taxonomy.dll'

function New-SearchNavigation() 
{
    param(
        [Parameter(Mandatory=$true)]$siteurl,
        [Parameter(Mandatory=$false)][System.Net.NetworkCredential]$credentials
    )
    try
    {
##############################################################################

function AddSearchLink([string]$searchsiteUrl, [string] $navTitle,[string] $navUrl){

 $ctx = New-Object Microsoft.SharePoint.Client.ClientContext($siteurl) 
 $ctx.Credentials = $credentials
$rootWeb = $ctx.Web  
$sites  = $rootWeb.Webs

$ctx.Load($rootWeb) 
$ctx.Load($sites) 
$ctx.ExecuteQuery() 

foreach($searchweb in $sites) 
{ 

  $ctx.Load($searchweb) 
    $ctx.ExecuteQuery() 
    if ($searchweb.title -contains "search" ){

    Write-Host $searchweb.Title "-" $searchweb.Url  
     $node=New-Object Microsoft.SharePoint.Navigation.SPNavigationNode -argumentlist @($navTitle,$navUrl,$true);

 $searchweb.Navigation.AddToSearchNav($node);

 $searchweb.Update()
    }
} 
 #$searchweb=Get-SPWeb $searchsiteUrl

##DeleteSearchLink -searchsiteUrl $searchsiteUrl -navTitle $navTitle

}
    AddSearchLink("mysite/search", "TEST", "/search/test.aspx")

}
    catch
    {
        Write-Host ("Error while creating search result page. Error -->> " + $_.Exception.Message) -ForegroundColor Red
        Write-Output("Error while creating search result page. Error -->> " + $_.Exception.Message)
    }   
}
$credentials = Get-Credential
$url = mysite

New-SearchNavigation $url $credentials

I get an error saying cannot find type [Microsoft.SharePoint.Navigation.SPNavigationNode]:

Try adding the type Microsoft.SharePoint.Client.NavigationNode and then switching Microsoft.SharePoint.Navigation.SPNavigationNode to Microsoft.SharePoint.Client.NavigationNode

SPNavigationNode is the server object model, to use the client object model, you want NavigationNode. See here for details.

However, unlike SPNavigationNode, NavigationNode does not take a constructor with two arguments, see here for NavigationNode and here for SPNavigationNode.
