Configure aeotec quad wallmote to dim light

Hello friends
I have a aeotec quad wallmote and an aeotec dimmer.
I successfully connected them to the smart things hub and I can switch the light and dim it from the app on my phone.

However, from the wallmote, I can only switch the light on and off.
I followed the instruction in the following link and tried to configure group association 3 for dim, but when I hold down the button or swiping it up and down, it won’t dim.

what am I missing.

Thanks, Nadav
