Turn on Revival Rewards

As with Welcome Rewards, enable the feature and click Setup next to Revival Rewards. Choose a role to ping when chat dies, or use Auto Setup. You can customize the revival message with the Customize button.

In Rewards channel setup, add a Reward channel for Welcome Rewards and Revival Rewards. Enable Welcome, Revival, and Hospitality routing, preferably pointing each to your commands or bot channel. Auto Setup can configure these settings automatically.
