I'd like to create a new team containing people who would like to shadow our live on-call process. How can I add this team to the escalation policies of live teams, such that all alerts to a live team are also sent to members of the shadowing team?
I have tried adding escalation policies in the live team to alert the shadow team when new alerts are not acknowledged or closed within 0 minutes, but whenever I try this members of the shadow team are not alerted.
