following interface open when "west zap-gui" command use

after addition of cluster i generate 
 
 using this we can add cluster as above correct me if i'm wrong. 
 after generating cluster i use " west zap-generate " command showing error 
 path for "west zap-gui" on same path i use " west zap-generate" showing "No valid .zap file provided" because zap file inside the sample code light_bulb so at that location i use 
 "west zap-generate" command then showing error 
 " usage: west [-h] [-z ZEPHYR_BASE] [-v] [-q] [-V] <command> ... west: unknown command "zap-generate"; workspace /home/nistantritech/light_bulb_3 does not define this extension command -- try "west help" and "west -vv status " 
 
 Are you running the command from a terminal where the nRF Connect SDK environment is set up, such as an nRF Connect terminal in VS Code?
