Triggers can be invoked from your iPhone, iPad, Apple Watch, or HomePod via Shortcuts using the REST API. This is by far the easiest and most native way I have found to invoke triggers from iOS.

{TriggerName}: The name of your trigger.

For the macOS application, I had set the trigger to run as background, without reading this first. It caused the trigger to not show up in the web interface until I set it to foreground.

Would it be possible to remove the background option for the macOS app to avoid confusing people?
