custom_progress_callback.py

# This script demonstrates how to monitor the download progress by providing a custom callback function.
# By setting the 'progress_callback' parameter, the provided function will be called periodically with the current progress.
# This will disable the default progress bar and you can use your own progress bar or any other progress indicator.
# This is useful for updating a UI, logging progress, or executing other actions based on the download status.
