You can actually trigger an iOS shortcut using a workaround—if you have an older iPhone with a home button (which is the issue in my case).

Here’s how it works: you can configure your Flic button to simulate a home button press (double or triple clicks). Then, on your iPhone, go to Settings and set a multiple home button press (e.g., double or triple press) to trigger your shortcut.

The downside is that most modern iPhones no longer have a home button. Additionally, the Flic app doesn’t currently offer support for using the triple tap on the back of the phone (a feature available on newer iPhones) as an alternative to the triple click on the home button.
