如果用户不是某个安全组的成员，如何从 Teams 共享频道中删除用户？

Question

I'm trying to automate the removal of users from a shared channel that are not part of a dynamic security group. I think I'm heading down the right path, but I'm relatively new to PS scripting.

$securitygroupId = "The Security Group"
$channelgroupId = "The GroupId of the host AzureAD Group"
$channelname = "Name of the Shared Channel"

Get-TeamChannelUser -GroupId $channelgroupId -DisplayName $channelname |
    ForEach-Object {$channelusergroups = Get-AzureADUserMembership -ObjectId $_.UserId | Select ObjectId
                    if ($channelusergroups -NotContains $securitygroupId)
                        {Remove-TeamChannelUser -GroupId $channelgroupId -DisplayName $channelname -User $_.User
                        }
                   }

It removes the users right now even if they are in the security group.

I learned that if you put "-expand" after "select", the search will find the ObjectId of the security group in the pipeline. Hope this helps someone else! -Cheers
