Can you add Notification Support?

Thank you for such a great library, this is the best download progress listener that I could find, can you add notification support? so it can be more superb?

Thank you sir

No files, tests, or entry points are named. First clarify which notification platform and progress behavior are required, then inspect the library's existing download and upload progress integration. Done should include a defined notification experience and tests or documented verification for it.
