Okay, I see. Unfortunetly, I don't get how clearml tasks are intended to be used. Could you help me with that? (see code)

` def start_carla_factory():
task = # How do I create this task?

long_blocking_call_to_start_carla()

return task

pipe = PipelineController(
name="carla-autostart",
project="rlad/carla-servers",
version="0.0.1",
add_pipeline_tags=False,
)
pipe.add_step(name="start-carla", base_task_factory=start_carla_factory)
pipe.start() `
