webhook subscription topic attributed_sessions_first

[dan_sproutward]

The Webhook Subscriptions Topics page suggest that attributed_sessions_first is available but it isn't listed as an event when creating a new webhook under notifications.

How do I subscribe for this webhook subscription?

The answer is that these topics are not available from the notifications event drop down but have to be subscribed to from an app.
