On Indie and Studio you can send rival alerts straight into a Discord or Slack channel.
- Open Notifications.
- Under Discord & Slack, give the channel a name and paste its channel link. The page shows exactly where to find that link in Discord and in Slack.
- Click Connect channel, then Send test to see it arrive.
- On the Alerts page, tick Discord / Slack on the alerts you want there.
You can connect more than one channel, and remove one at any time.
Tip: if a channel shows Stopped, it was probably removed on the Discord or Slack side. Connect it again with a fresh link.
