Ikea 5 button Remote Controller not working


I just got my homey pro 2023.

I have connected all my Ikea lights through my hue bridge. As a test I wanted to see if the Old 5 button Remotes i had laying around could actually be usefull again. I connected two of these directly to the homey pro. Worked fine. But i cannot use them as input for my flows.

Nothing happens when try to select a button for input!

You have to assign the functions to the buttons by flows.
Button X has been pressed
execute action Y
