How to Get Friendly Description For Scheduled Task Trigger in Powershell

Following https://stackoverflow.com/a/32732879/1378356, I can get a scheduled task's trigger using this syntax:

$task = Get-ScheduledTask -TaskName "SomeTaskName"
$taskTrigger = $task.Triggers[0]
$taskTrigger

But how do I see the friendly name (which is displayed in the Task Scheduler UI), such as "At 8:00 am every Monday"?
