Kind of event that occured.
Notifications represent information that should be presented to the user immediately. At the moment, only chat message events have associated notifications.
Notifications should be displayed in an unobtrusive manner throughout the entire game. Notifications should disappear after a few seconds if not interacted with.
If your platform supports it, notifications should be able to be clicked or
tapped in order to open the relevant context for the event.
For a simple implementation of notification interactions, open url in a
web browser to present the relevant context. For example, a chat message
notification will open the thread the chat message was sent in.
For advanced implementations that implement a custom chat UI, use
rivet.api.identity.common#GlobalEvent$kind to determine what action to
take when the notification is interacted with. For example, if the global
event kind is rivet.api.identity.common#GlobalEventChatMessage, then open
the chat UI for the given thread.
RFC3339 timestamp.
