Getting all attachments when using mu4e-headers-for-each?

[Hippo Man]

In the headers buffer, I want to loop through a group of messages whose headers have been selected within a region, and I want to access all the attachments from any messages that contain them.

I am able to successfully loop through the messages, but the :parts attribute is missing for each of these messages. What do I need to do in order to get the message parts by means of the following function? ...

(defun process-all-attachments ()
  (interactive)
  (let ((start (if (region-active-p) (region-beginning) (point-min)))
        (end (if (region-active-p) (region-end) (point-max))))
    (save-excursion
      (save-restriction
        (narrow-to-region start end)
        (mu4e-headers-for-each
         (lambda (msg)
          (let ((flags (mu4e-message-field msg :flags)))
             (when (member 'attach flags)
                ;; WHAT DO I DO HERE TO GET ALL OF THE MESSAGE PARTS???
                ))))))))

Thank you in advance.

In headers-mode, mu4e uses reduced message-objects (for performance
reasons), which don't include e.g. message bodies, mime-parts etc.

If you want to, say, extract the attachments for such messages, one
possibility would be to use the :path field and shell out to "mu
extract".

Kind regards,
Dirk.
