Configuring a scene?

Hi,
I have some devices with zigbee scene cluster support. Scene support is like a group, but instead of just on/off you get to set the attributes of each device (e.g. brightness, colour) when the scene is active.

Does anyone know how to configure a zigbee scene with zigbee2mqtt?

Thanks in advance!
