Please provide equivalents to `ToastButton` in Windows Community Toolkit

There is no way to create ToastButtonSnooze or ToastButtonDismiss using AppNotificationBuilder and AppNotificationButton.

<action activationType="system" arguments="dismiss" content=""/>

activationType="system" is necessary to use the default localized strings.

Snooze/dismiss

Thanks for proposing this feature!

For WinAppSDK 1.2, we wanted to cover as many core features as we could with intentions to reach 1:1 parity or close to it with the UWP ToastContentBuilder. We will continue to add more features in future releases and prioritize the features that customers are wanting most.
