If you wish to use groups you would need to also install drivers for the lights that support groups. e.g Zigbee Light Multifunction Mc from (NEW RELEASE) Beta Edge Driver Zigbee Light Multifunction Mc - #33 by Mariano_Colmenarejo for each of your bulbs. This requires that your bulbs are supported by that driver.
If you are using Styrbar then you have the option of also doing direct binding using only my driver, it can be tricky to setup but it should work. It can be tricky to setup, you can follow the instructions to do that here → Zigbee Button + Groups - Alpha Test - #29 by lmullineux To find the device addresses for each bulb you can use the following Zigbee Button + Groups - Alpha Test - #30 by lmullineux
Both solutions should be considered experimental.
