Yes. It solved the problem discussed here with the following configuration:

;;;;;;;;;;;;;;;;;;; begin config
;; https://github.com/emacs-helm/helm/wiki#if-installed-from-source
;; First issue the following command
/home/werner/.emacs.d/straight/repos/helm$ make
(use-package helm :config (require 'helm-autoloads))

(use-package helm-bibtex
  :init
  (setq
   bibtex-completion-pdf-field "File"
   ;;https://github.com/tmalsburg/helm-bibtex#insert-latex-cite-commands
   bibtex-completion-cite-prompt-for-optional-arguments nil)

  :bind-keymap
  ("<menu>" . helm-command-prefix)
  :bind
  (
   :map helm-command-map
   ("b" . helm-bibtex)
   ("B" . helm-bibtex-with-local-bibliography)
   ("n" . helm-bibtex-with-notes)
   ("<menu>" . helm-resume)
   )
  )
;;;;;;;;;;;;;;;;;;; end config

See the attached screenshot for the completion results, which include
`bibtex-completion-cite-commands`.
