Short flash for HUE bulp if someone PRESS Ring doorbell

I don’t know why you repeat the information about the “flow category”? Especially since you should now be aware that you are asking your questions in the wrong category. The “Questions & Help” category would have been the correct category. Or the relevant App threads.
@Dijker, @Caseda, @Jamie could someone of you move the post to the right category? Thanks!

Have you searched in the relevant thread to see if these functions are even possible with Homey? You can also submit a feature request to the app developer in this thread.
These points are already on the ToDo list regarding movement detection. Maybe this is exactly what you need:

It would be important to know which Hue app you are using. I myself use the “Philips Hue, without the bridge” app (by J. Bendz) and can say from my own experience that there is a flow card for this and it works:

And if I have a look at the Philips Hue App (by Athom) in the App Store, there is also a flow card for flashing the bulb:

What I do not know, if this will work with any model of lamp/bulb.
