For this function:

(defun my-function ()
  (interactive nil '(text-mode mail-mode))
  (message "Hello"))

> If MODES is present, it should be a list of mode names (symbols) that

I expect that M-x TAB shows it in this mail-mode, but it does not show
it this time. That is one of expectations, among several.

In general, I would like to setup functions NOT to show in modes where
they should not be shown.

I feel this function does not work.

If you have working example, show me.
