SharePoint 2013 - 由PowerShell添加的Webpart，但在Web浏览器上按编辑模式查看时不显示

Question

***我使用SharePoint Powershell（2013）将webpart添加到页面

*** Affer从powershell添加了webpart成功，然后我转到页面，我看到webpart被添加到页面中（我还在Web部件页维护中看到了webpart）

***但是当我按编辑模式显示页面时，我找不到网页部分。

***你能帮我解决一下如何从powershell添加webpart，但是我仍然可以在网页浏览器的页面编辑模式下编辑webpart吗？

这是我的powershell脚本：

function NewGuid(){
    $id = [System.Guid]::NewGuid().ToString()
    return "g_" + $id.Replace("-","_") 
}

function Add-ContentEditorWebPart()
{
    $SiteURL = "https://insiderdev.connorgp.com"
    $pageUrl = "https://insiderdev.connorgp.com/ConnorGroup/SitePages/NhanTest1.aspx"
    $webpartzone = "Header"
    $index = 1
    $title = "Content Editor"

    $site = new-object Microsoft.SharePoint.SPSite($SiteURL)
    $web=$site.OpenWeb()

    $webpartmanager = $web.GetLimitedWebPartManager($pageUrl, [System.Web.UI.WebControls.WebParts.PersonalizationScope]::Shared)

    $webpart = new-object Microsoft.SharePoint.WebPartPages.ContentEditorWebPart    
    $webpart.ChromeType = "None"
    $webpart.Title = $title 
    $webpart.ID = NewGuid
    $webpart.FrameType = "None" 
    $webpart.CatalogIconImageUrl = "/_layouts/15/images/mscontl.gif"
    $webpart.PartImageLarge = "/_layouts/15/images/mscontl.gif"

    $content = "Test Webpart added"
    $docXml = New-Object System.Xml.XmlDocument
    $contentXml = $docXml.CreateElement("Content")
    $contentXml.set_InnerText($content)
    $docXml.AppendChild($contentXml)    
    $webpart.Content = $contentXml

    $webpartmanager.AddWebPart($webpart, $webpartzone, $index)

    $web.Close()
    $site.Close()
}
