[Q] :':fzf-tab:complete:cd:*' not working but ':fzf-tab:*' works

[indramal]

zstyle ':fzf-tab:complete:cd:*' fzf-preview 'ls --color=always $realpath' this code is not working but zstyle ':fzf-tab:*' fzf-preview 'ls --color=always $realpath' code is working for me. I use "cd" space and tab for not working code. I use "cd" tab for working code. It also work for "c" and tab.
