Is there a lisp trick for adding arguments to the function called by `org-map-entries`?

I have the following function:

(cl-defun org-lms-return-all-assignments (&optional (send-all nil) (also-mail nil) (post-to-lms t) )
  "By default mail all subtrees 'READY' to student recipients, unless SEND-ALL is non-nil.
In that case, send all marked 'READY' or 'TODO'."
  (interactive)
  (message "Mailing all READY subtrees to students")
  (let ((send-condition
         (if send-all
             `(or (string= (org-element-property :todo-keyword item) "READY")
                  (string= (org-element-property :todo-keyword item) "TODO") )
           `(string= (org-element-property :todo-keyword item) "READY")
           )))
    (org-map-entries
     #'ol-send-just-one))
  (org-cycle-hide-drawers 'all))

I'd like to relay some of hte functions arguments to the one called internally to do the work.  ~(ol-send-just-one~ takes an ~also-mail~ and a ~post-to-lms~ parameter,just like ~org-lms-return-all-assignments~, but I'm not sure how to trick org-map-entries into passing those arguments on. Any hints?  Thank you!
