How do I properly complete a task in a Python console? If I run the code

from clearml import Task, TaskTypes
task = Task.init(project_name='FirstTrial', task_name='first_trial', task_type=TaskTypes.training)
PACKAGE_VERSION = '0.4.1'
dataset_name = "Demodata"
task.mark_completed()

I get

<clearml.backend_api.session.callresult.CallResult object at 0x0000024E3A63A490>
2023-02-14 13:39:40,387 - clearml.Task - WARNING - ### TASK STOPPED - USER ABORTED - STATUS CHANGED ###
Process finished with exit code 15

and nothing appears in "execution" -> "installed packages".
