matter 幻彩灯带自定义开发，局域网通过matter cluster控制的问题

[tonish]

CBU matter sdk3.8.4
1，局域网app 下发模式dp21，被sdk拦截转成matter cluster并报错，
Endpoint=1 Cluster=0x125D_FC01 Command=0x0000_0000 status 0xc3 (UNSUPPORTED_CLUSTER) (no additional context)
请教，cluster该如何设置
2，另外联网成功app操作，有 DP ID 21 Invalid
3，报[SessionManager.cpp:722] Data received on an unknown session (LSID=29997). Dropping it!

局域网下走的是matter通路，需要注册dp21对应的attribute_id = 21 到自定义cluster_id=0x125dfc01上面。就如同ON_OFF_ATTRIBUTE注册到ON_OFF_CLUSTER上一样。不知你这一步是否有设置
