which-key labels not shown in prefix-command keymaps

[ghost]

Hello,
I am using the following configuration (inspired by Spacemacs):

(general-define-key
 :states 'normal
 "SPC" '(:prefix-command my/space-menu-map :wk "S P A C E  menu")
 )

(general-define-key
 :keymaps 'my/space-menu-map
 "b" '(:prefix-command my/buffer-menu-map :wk "Buffer…")
 "f" '(:prefix-command my/file-menu-map :wk "File…")
 "h" '(:prefix-command my/help-menu-map :wk "Help…")
 )

(general-define-key
 :keymaps 'my/file-menu-map
 "s" '(save-buffer :wk "save")
 )

This works fine, except that the which-key labels are not shown (I just see the keymap or command name). Which-key does work outside of :prefix-command keymaps.

Use keymap-based replacements instead of :wk.

For the prefix commands, you might be able to just replace :wk with :prefix-name. If not, you will have to bind to a cons (e.g. (cons "Buffer…" 'my/buffer-menu-map).

#503 should be updated (or a new PR added) to improve the documentation for which key.
