Notification button component

<wy-notification-button> | WyNotificationButton

Weavy automatically generates notifications for reactions, mentions, and other activity within your app. The Notification Button component renders a notifications button complete with a realtime badge for the number of unread notifications. When clicked, the button opens a built in overlay displaying the full list of notifications.

The notification button component can optionally be tailored to only show notifications for a specific app or notifications of a specific type, such as mentions or reactions.

Complement this with the Notification toasts component to also get realtime in-app notifications or browser notifications.
