Is the Snackbar example correct?

Fellows,

I was trying to follow this example: https://developer.android.com/develop/ui/compose/components/snackbar

But I cannot find how to enable both options like in the image:

I want to have the X to dismiss and the action. Is it possible? Or is the image wrong? Since I cannot find the way to enable it. Thanks.
