How do I connect a Nue Zigbee 3 gang light switch

Hi, I've just installed a Nue Zigbee 3 gang light switch & a Scene Switch. I have searched & found both of them, How do I find the 3 individual switches on the light switch?
The Scene Switch has also been found, although is is shown as a 'SmartThings Presence Sensor' how do I adjust this< or doesn't it matter, I think it would?

I don’t think those devices are supported directly but using SEARCH should get you this link which has some info....
