  -exposes toast component's wrapper style prop
  +The `toast` function now exposes a `containerStyle` property you can use to
  +override the default styles for the toast container.
  +```jsx live=false
  +function Example() {
  + // Via instantiation
  + const toast = useToast({
  + position: "top",
  + title: "Container style is customizable",
  + containerStyle: {
  + maxWidth: "100%",
  + },
  + })
  +
  + // Or via trigger
  + return (
  + <Button
  + onClick={() => {
  + toast({
  + containerStyle: {
  + maxWidth: '100%',
  + },
  + })
  + }}
  + >
  + Click me to show toast with custom container style.
  + </Button>
  + )
  +}
