Love this. I'm on an extended trip right now so I'm be a bit slow for review. I will be back home and have final review on this within a couple weeks. Everything looks very good though, thank you for the contribution!

Hey @juftin, hope your vacation went well! Please let me know if there's anything I can update on this.

Any updates here? The discord integration would be useful. Happy to pick this up & run, but def don't want to step on any feet!

I haven't spent any time on this, I can take a closer look soon though. In the meantime Discord notifications are supported via the AppRise notification provider

This was my first time using Apprise, but it was easier to setup than I thought.

There may be some additional behavior that this PR adds, but I haven't read it in depth at this point.

For future readers, create a webhook on your discord server, copy the URL and set APPRISE_URL with that value (either with camply configure or export APPRISE_URL={my_discord_webhook}). You can then run the test-notification command straight away.
