Hello, sorry to jump in the "I've got an issue"
I'm currently following the "Update to Prefect 2.0: Notifications" YouTube and have followed the tutorial to the letter but when running the flow for "notification_block" I get the following error:- "RuntimeWarning: coroutine 'SlackWebhook.notify' was never awaited slack_webhook_block.notify("Hello from Prefect!")"
When using the "Notifications" within the Prefect Cloud 2.0 for the Slack notification it works fine when the flow is completed.
