Notify2.UninittedError: You must call notify2.init() before using the notification features how to fix?

Question

linux

Watched how to make notifications in Linux. I used the notify2 library. Displays quietly notifications and ok. But then it stopped displaying, throwing the error notify2.UninittedError: You must call notify2.init() before using the notification features
How to fix this?
see code

def notifications (progress, timeout):
    ICON_PATH = "spotidownload.svg"

    n = notify2.Notification(f"SpotiDownload - {progress}", icon = ICON_PATH)
    n.set_urgency(notify2.URGENCY_NORMAL)
    n.set_timeout(timeout)

    n.show()
    n.close()

Answer 1

Add a line to the beginning
notify2.init("SpotiDownload")
