+ℹ️ **Note** ℹ️
+Native push buttons can be styled as text-only, text with an icon, or icon-only. Currently, text-only push buttons are supported. To create an icon-only button, use the `MacosIconButton` widget.
 
 Here's an example of how to create a basic push button:
 
 ```dart
 PushButton(
   child: Text('button'),
-  buttonSize: ButtonSize.large,
+  controlSize: ControlSize.regular,
   onPressed: () {
     print('button pressed');
   },
