New Post: how to use a Group Managed service account to run a schedule task and make it "Run whether user is logged on or not"?

how can I use a Group Managed service account to run a schedule task and make it "Run whether user is logged on or not"?
https://technet.microsoft.com/en-us/library/hh831782.aspx this is some thing about Group Managed service accounts,
I tried several ways:
. use AddTask directly

    TaskService.Instance.AddTask("Test", new MST.DailyTrigger { DaysInterval = 1 },
                                    new MST.ExecAction("notepad.exe", "c:\\test.log", "c:\\program files\\"), "myDomain\\testMSA$", null, TaskLogonType.None);

only TaskLogonType.None can AddTask successfully, but the task is "Run only when user is logged on"

. RegisterTaskDefinition

MyTask.Folder.RegisterTaskDefinition(MyTask.Name, MyTask.Definition,
                            TaskCreation.CreateOrUpdate, "rmad\\testMSA$", null, TaskLogonType.None);

TaskLogonType.InteractiveToken and TaskLogonType.None can AddTask successfully, but the task is "Run only when user is logged on"

. change Principal

MyTask.Definition.Principal.UserId = "rmad\\testMSA$";
MyTask.Definition.Principal.LogonType = TaskLogonType.None;
MyTask.Folder.RegisterTaskDefinition(MyTask.Name, MyTask.Definition);

only TaskLogonType.InteractiveToken can AddTask successfully, but the task is "Run only when user is logged on"
at the same time, when I assigned TaskLogonType.None and TaskLogonType.Group, I got error "Value does not fall within the expected range"

In short, I can create a schedule task using Group Managed service accounts to run, but just can't make the task "Run whether user is logged on or not"
