Programming Main Button on Zooz Scene Controller

I have just installed a Zooz ZEN32 scene controller including the device handler. I programmed the 4 buttons and that works fine. I am now trying to program the main button but the main button does not show up in the devices or automations lists.Does the main button have to be paired separately? I’m stuck here. Any suggestions? Tx

It does show as a switch

and also you can do automations
