Adds a button with label [code]text[/code] and a custom [code]action[/code] to the dialog and returns the created button. [code]action[/code] will be passed to the [signal custom_action] signal when pressed.

Removes the [code]button[/code] from the dialog. Does NOT free the [code]button[/code]. The [code]button[/code] must be a [Button] added with [method add_button] or [method add_cancel] method. After removal, pressing the [code]button[/code] will no longer emit this dialog's [signal custom_action] signal or cancel this dialog.
If [code]true[/code], the dialog is hidden when the OK button is pressed. You can set it to [code]false[/code] if you want to do e.g. input validation when receiving the [signal confirmed] signal, and handle hiding the dialog in your own logic.
[b]Note:[/b] Some nodes derived from this class can have a different default value, and potentially their own built-in logic overriding this setting. For example [FileDialog] defaults to [code]false[/code], and has its own input validation code that is called when you press OK, which eventually hides the dialog if the input is valid. As such, this property can't be used in [FileDialog] to disable hiding the dialog when pressing OK.
