Powershell CSOM多选项复选框

我在这方面已经到了互联网的尽头。这种资源的许多变体

我正在运行O365 Sharepoint，我有一个多复选框列表或多选择Web部件

当我查询现有条目时，数据以数组的形式返回。当我将数组发送到此字段时，它不会选中复选框，尽管字符串的值是可见的

Multi-Value  {option1, option2, option3}

我不能让它工作。它甚至与我的代码格式不一样

Add-Type -Path 'C:\ServOps\com\SharepointRuntimes\Microsoft.SharePoint.Client.dll'
Add-Type -Path 'C:\ServOps\com\SharepointRuntimes\Microsoft.SharePoint.Client.Runtime.dll'
$url = "https://my.foo.sharepoint"

Function Write-ListItems([Microsoft.SharePoint.Client.ClientContext]$Context, [String]$ListTitle) {
$Context.ExecuteQuery()
# <context>
#    <description>The list must be fetched before ListItemCreationInformation binds to put data</description>
# </context>
$List = $Context.Web.Lists.GetByTitle($ListTitle)

$Context.Load($List)
$Context.ExecuteQuery()


# <context>
#    <description></description>
# </context>
$ListItemCreationInformation = New-Object 
Microsoft.SharePoint.Client.ListItemCreationInformation
$NewListItem = $List.AddItem($ListItemCreationInformation)
$NewListItem["Title"] = $TASK
$NewListItem["Approximate_x0020_delivery_x0020"] = $AVERAGE_DELIVERY_TIME_SLA 

$NewListItem.Update()
$Context.ExecuteQuery()
}
$context = Get-SPOContext -Url $Url -UserName $UserName -Password $Password
Write-ListItems -Context $context -ListTitle "My Sharepoint"
$context.Dispose()

这是我的测试脚本

我第一件事就是尝试了这个。不幸的是，这并没有选中复选框，它只是添加了一个逗号分隔的列表。谢谢。这个脚本可以在我的测试环境中运行，你可以通过创建一个带有B C的测试字段来进行测试吗？它确实可以在添加数据的情况下运行，但是没有选中复选框。当我点击表单元素在GUI中展开（其折叠|隐藏）时，我发送的数据被清除，复选框不被选中。我正在使用O365版本
