How to trigger an App Designer UI component's callbacks programatically, like `notify()`

Assume there is a uibutton in an App Designer uifigure referenced as app.Button, and I'd like to trigger its callbacks programatically. There seems to a function called notify(), however, it doesn't seem to work with uifigure elements, maybe because of the NotifyAccess. For exampmle, if I:
notify(app.Button,'ButtonPushed')
will give an error:
Error using matlab.ui.control.Button/notify
Cannot notify listeners of event 'ButtonPushed' in class 'matlab.ui.control.Button'.
I wonder if there is some method to trigger the callbacks programatically, instead of actually calling the defined callbacks function with a fabricated EventData or struct?
Cheers

Do you want to do this in the scope of testing, or to reuse the functionality of the button callback? For the former, look at matlab.uitest.TestCase.press(). For the latter, put whatever functionality you want in another function and just call it directly.

Possibly I read from the doc listener events are broadcast, not sure if it arrives automatically to children. In any case the same errors occurs with btn.
