[Solved] Hue smart button with Hue (bridge) app

I added a Hue smart button to the Philips Hue app on iPad. In the Philips Hue app I did not configure anything, because I wanna use it as a smart button with Homey. I added the button to the Homey hardware list.
So far so good.
I created a flow: if button pressed short blink light, but then nothing is happening.
Is it possible to use the button this way?

Edit: flow was for some reason disabled
