@joshuapsteele Absolutely! Any way you can run a shortcut you can use this. Lock Screen widget. Control Center widget. But the way most similar to Action Button activation would be with Back Tap. Settings → Accessibility → Touch → Back Tap → Set it to double or triple tap.

A smartphone screen shows the "Back Tap" settings with options: "Double Tap" for "Control Center" and "Triple Tap" for "Quick Shortcuts." The background is a gradient of pink and purple.
