The Slack integration allows for notifications to be easily configured and sent to Slack channels without using automation. Currently, it's only possible to replicate this feature with ClickUp Chat by using an automation and hence automation credits. This seems counter-intuitive if you'd like us to move from Slack to ClickUp Chat.

Furthermore, when using an automation, the notification will come from a user, whereas the Slack integration displays the message from a 'ClickUp bot'.
