Is it possible to call inside an elisp function the interactive version of (describe-function)?

Started with using completing-read for inputting the function name, but does not

look that the use of completing-read is appropriate, because completing-read only

accepts completion from a predefined list.

(defun ehelp (actm)
  "Describe emacs help commands."

  (interactive
   (list
    (let* ( (cseq '("variable" "function")) )
      (completing-read "Emacs_help: " cseq nil t "function"))))

  (pcase actm
    ("function"
        (describe-function (completing-read "function: " nil nil nil)))
    (_ (message "TODO"))) )

`call-interactively' but often it's not a good thing to do ...

That whole division is trouble IMO, but it is what it is, so
what one can do is use is sensibly at least ...

(completing-read PROMPT COLLECTION &optional PREDICATE REQUIRE-MATCH
INITIAL-INPUT HIST DEF INHERIT-INPUT-METHOD)

Read a string in the minibuffer, with completion.
PROMPT is a string to prompt with; normally it ends in a colon and a space.
COLLECTION can be a list of strings, an alist, an obarray or a hash table.
COLLECTION can also be a function to do the completion itself.

Function need not be predefined, function may run with some
dynamically generated data.
