See (info "(elisp) Manipulating Buttons"), in particular:

 -- Function: button-activate button &optional use-mouse-action
     Call BUTTON's ‘action’ property (i.e., invoke the function that is
     the value of that property, passing it the single argument BUTTON).
   [...]

However, since in your case the argument `button' is not used in the
body of the function, if you enable lexical binding in the file
containing it and byte-compile the file, you'll get a warning: "Unused
lexical argument ‘button’".  To avoid that warning, you can use
e.g. `_button' (or just `_') as the argument (cf. (info "(elisp)
Converting to Lexical Binding")).
