Try this one (will be fixed in 5.13):

;; Make appt aware of appointments from the agenda
(defun org-agenda-to-appt (&optional filter)
  "Activate appointments found in `org-agenda-files'.
When prefixed, prompt for a regular expression and use it as a
filter: only add entries if they match this regular expression.

FILTER can be a string. In this case, use this string as a
regular expression to filter results.

FILTER can also be an alist, with the car of each cell being
either 'headline or 'category.  For example:

  '((headline \"IMPORTANT\")
    (category \"Work\"))

will only add headlines containing IMPORTANT or headlines
belonging to the category \"Work\"."
  (interactive "P")
  (require 'org)
  (require 'calendar)
  (if (equal filter '(4))
      (setq filter (read-from-minibuffer "Regexp filter: ")))
  (let* ((cnt 0) ; count added events
	 (today (org-date-to-gregorian 
		 (time-to-days (current-time))))
	 (files org-agenda-files) entries file)
    ;; Get all entries which may contain an appt
    (while (setq file (pop files))
      (setq entries 
	    (append entries 
		    (org-agenda-get-day-entries 
		     file today 
		     :timestamp :scheduled :deadline))))
    (setq entries (delq nil entries))
    ;; Map thru entries and find if they pass thru the filter
    (mapc 
     (lambda(x)
       (let* ((evt (org-trim (get-text-property 1 'txt x)))
	      (cat (get-text-property 1 'org-category x))
	      (tod (get-text-property 1 'time-of-day x))
	      (ok (or (null filter)
		      (and (stringp filter) (string-match filter evt))
		      (and (listp filter)
			   (or (string-match 
				(cadr (assoc 'category filter)) cat)
			       (string-match 
				(cadr (assoc 'headline filter)) evt))))))
	 ;; FIXME Shall we remove text-properties for the appt text?
	 ;; (setq evt (set-text-properties 0 (length evt) nil evt))
	 (when (and ok tod)
	   (setq tod (number-to-string tod)
		 tod (when (string-match 
			    "\\([0-9]\\{1,2\\}\\)\\([0-9]\\{2\\}\\)" tod)
		       (concat (match-string 1 tod) ":"
			       (match-string 2 tod))))
	   (appt-add tod evt)
	   (setq cnt (1+ cnt))))) entries)
    (message "Added %d event%s for today" cnt (if (> cnt 1) "s" ""))))
