zigbee sdk 4.1 add CO2 and HCHO cluster

[zero]

Hi，

In the 07-5123-07-zigbee-cluster-library-specification specification, I see clusters that support CO2 and HCHO, but I did not see any definitions of CO2 and HCHO (cluster) in the latest zigbee sdk 4.1. Our current Can the zigbee protocol stack support CO2 and HCHO sensor?
If supported, how can I report CO2 and HCHO data to the gateway?

It is probably just a matter of implementing the clusters along the lines of the Pressure cluster that is included with the SDK. I think somewhere around SDK 3.1 or maybe 4.0, the pressure cluster was included as an example for how a custom cluster should be implemented, despite pressure being a standard cluster.

The pressure cluster defines the cluster id on zb_zcl_common.h. Can I also add CO2 and HCHO cluster id in zb_zcl_common.h?
