In case anyone else hasn't heard of this, it describes itself as

  Atuin replaces your existing shell history with a SQLite database, and
  records additional context for your commands. Additionally, it
  provides optional and fully encrypted synchronisation of your history
  between machines, via an Atuin server.

Do you know about the `bash-completion' package?  It enhances
`read-shell-command' completion with completion data provided by bash.
It is very easy to set up,

  (use-package bash-completion :ensure t
    :init (bash-completion-setup))

should do it.

I am not sure if you meant to attach any code, but that would probably
be the best place to start.
