Dimming Control via switch - WIZ Bulbs

I have 4 wiz led RBG bulbs that are permanently powered.

I would like to use an Inovelli dimmer wall switch (or similar) with the air gap disabled to dim the group of 4 bulbs. I have created a lighting group to associate the 4 bulbs together

I need some help on how I map the dimmer paddles on the switch to the ‘virtual’ dimmer for the lighting group. I have read through there FAQ but still cannot understand how to do this

Thanks in advance
