add-zle-hook-widget
zsh: command not found: add-zle-hook-widget

locate add-zle-hook-widget
/usr/local/share/zsh/5.8/functions/_add-zle-hook-widget
/usr/local/share/zsh/5.8/functions/_add-zle-hook-widget.zwc
/usr/local/share/zsh/5.8/functions/add-zle-hook-widget
/usr/local/share/zsh/5.8/functions/add-zle-hook-widget.zwc

echo $fpath
/root/scripts//zsh/functions/zle/  /usr/local/share/zsh/5.8/functions/

why the command is not found? Should I do something to load the functions
from fpath?
thanks
