I am a new user to doom emacs . I was trying to global set the key C-f to +vertico/consult-fd and C-b to consult-buffer but the keys kept the same function even after the command

(global-unset-key (kbd "C-f" ))

(global-unset-key (kbd "C-b" ))

(define-prefix-command 'fuzzy-fd)

(global-set-key (kbd "C-f") fuzzy-fd)

(define-prefix-command 'buffer-consult)

(global-set-key (kbd "C-b") buffer-consult)

(global-set-key (kbd "C-f") '+vertico/consult-fd)

(global-set-key (kbd "C-b") 'consult-buffer )
