Slack Notifications through existing Slack app
I'm trying to understand how the Novu <> Slack integration works beyond just adding a webhook to a Slack App. We already have a Slack App our customers use to interact with our app, and if I want to allow them to use this existing Slack App to either receive notifications directly to a user, or to a Slack channel the Slack App is already in (i.e. #app-notifications), I'm unsure if this is natively supported by Novu or if my application should handle the notification and then push it to our Slack app depending on the Novu configuration for that user and notification.
