Notify plugin: send push notifications about system events via Apprise

[Greelan]

I've just created a new plugin: Notify.

It uses Apprise as the backend, to allow push notifications about a bunch of different system events to be sent to any of the over 140 services supported by Apprise (Telegram, Pushover, ntfy, Gotify, Discord, Slack, Matrix, email, and so on...).

Check it out.
