setSuppressNotification
open fun setSuppressNotification(shouldSuppressNotif: Boolean): NotificationCompat.BubbleMetadata.Builder(source)
If set and the app posting the bubble is in the foreground, the bubble will be posted without the associated notification in the notification shade.
If the app posting the bubble is not in the foreground this flag has no effect.
Generally this flag should only be set if the user has performed an action to request or create a bubble, or if the user has seen the content in the notification and the notification is no longer relevant.
