I just had a look at the details of this, this code puts a directive in
the scoreheader (with nothing in the LilyPond, ie no prefix or postfix
fields set) and displays itself as a button (that is what the
DENEMO_OVERRIDE_GRAPHIC does) with the text from the display field.

(let ((tag "test"))
     (d-DirectivePut-scoreheader-override tag DENEMO_OVERRIDE_GRAPHIC)
     (d-DirectivePut-scoreheader-display tag "something"))

the tag used, in this case "test", does not match any action (there is
no command d-test), so clicking on it just gives the advanced edit.

another example:

(let ((tag "test"))
    (d-DirectivePut-movementcontrol-override tag
DENEMO_OVERRIDE_GRAPHIC)
     (d-DirectivePut-movementcontrol-display tag "something"))

this puts the button on the movement titles button bar. If you used a
real command for the tag, the button would execute that command. For
example
(let ((tag "NewScore"))
    (d-DirectivePut-movementcontrol-override tag DENEMO_OVERRIDE_GRAPHIC)
     (d-DirectivePut-movementcontrol-display tag "start new"))

creates a button that runs the NewScore command ...
