Не могу передать массив строк функции в Powershell

У меня есть следующий скрипт под названием vms.ps1:

# Definições das VMs e grupos
$VMPaths = @{
    "goad1" = "E:\GOAD\ad\GOAD\providers\vmware\.vagrant\machines\GOAD-DC01\vmware_desktop\d293bfc4-dc8c-4e82-9704-1506af10c065\WindowsServer2019.vmx"

# Função para suspender VMs
function Suspend-VMs {

# Função para parar VMs
function Stop-VMs {

# Função para desligar VMs

    ...
}

Моя идея — запустить этот скрипт из ALIAS в терминале.

Мой powershell $ПРОФИЛЬ:

. "F:\vmware\vms.ps1"

function vm {
    param (
        [string]$Command,
        [string[]]$VMNames
    )
    
    switch ($Command) {
        "start" { 
            if ($VMNames[0] -eq "--group") {
                Start-VMs -VMNames $VMNames
            } else {
                Start-VMs -VMNames $VMNames
            }
        }
        "suspend" { Suspend-VMs @($VMNames) }
        "stop" { Stop-VMs @($VMNames) }
        "poweroff" { PowerOff-VMs @($VMNames) }
        "list" { List-VMs }
        default { Write-Host "Comando desconhecido: $Command" -ForegroundColor Red }
    }
}

Когда я бегу:

vm list: работа

vm start syslog: работа

vm suspend syslog: работа

Но:

vm start --group goad: Не работай.

❯ vm start --group goad
MethodInvocationException: F:\vmware\vms.ps1:93
Line |
  93 |          if ($VMGroups.ContainsKey($groupName)) {
     |              ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
     | Exception calling "ContainsKey" with "1" argument(s): "Value cannot be null. (Parameter 'key')"
VM não encontrada: --group

Я хочу этого, когда ставлю:

vm start --group goad

Скрипт запускает все виртуальные машины, находящиеся внутри группы goad в $VMGroups.
