This needs iOS 27, because iOS 26 cannot run a shortcut when a notification arrives.
You do not need this for On this phone or Apple's cloud. Those never open Shortcuts.
Setting it up
The bridge is also what runs a step's shortcuts in the background, so you may have it already. If you have not:
- On the Describe page, with ChatGPT chosen, tap Write in the background. It appears once Routine Run Ask has run at least once. It is also under Triggers → … → The bridge.
- Follow the page: add the Routine Run Bridge shortcut, then make one automation in Shortcuts. When I get a notification from Routine Run → run Routine Run Bridge, set to run immediately.
The automation cannot be shared as a link, so this part is done by hand once.
While it is asking
The page says "Asking … in the background" with Cancel. You can close the page. The answer waits until you open the notification or the app.
ChatGPT, talk it through always opens in front, because a chat needs you.
