Automatically delete scheduled task using Python and Task Scheduler

Question

I am working on a Python script to create tasks in the Windows Task Scheduler using the win32com.client module. I want to include functionality to automatically delete these tasks after a certain period. Task scheduling function works fine.

I've tried to set the task to delete after a specified time using set_delete_expired_task_after, but it doesn't seem to work as expected.

How can I properly set up automatic deletion of scheduled tasks in Python?

import win32com.client

    date: str,
    hour: str,

    path_to_executable: str,
    path_to_execution_folder: str,
):
    """Function responsible for create a task on the task scheduler

        hour (str): Hour that the automation shoud be executed, must follow the pattern "HH:mm:ss"
        frequency (str): Frequency that the task will run, could be ["Unique", "Daily", "Weekly", "Monthly"]

    scheduler = win32com.client.Dispatch("Schedule.Service")
