Is there a way to mention/tag a user or group in Slack when sending a notification from Prefect Automation? I'm using

<@U03MK7Z2ULQ>

and

<!subteam^S037DR39NGP>

in the message body, but they just come as plain text. Looks like the message body is sanitized by Prefect. Does anyone have a similar issue or knows how to get it working? 🙏
