Options to trigger shortcut?

So far there are three methods I am aware of to trigger a shortcut in the native iOS Shortcut app:

• Use Siri
• Tap the shortcut in the iOS Shortcut app
• use personal automation

All of these require me to do something. Are there any other possibilities to do so? Background: I am running home assistant and HomeKit and would like to trigger a shortcut using intercom, to announce text to people in certain rooms/areas using HomePods there.
