Head over the escalations section on the dashboard and click on new escalation
Make sure to give a good identifiable name based on the team members in it.
Add multiple escalation levels
Add a time to wait before automatically escalating if incident is open (not acknowledged or resolved)
If you would like to receive simultaneous alerts for either you, your team or Slack, Teams, etc then we highly recommend adding multiple alerts in one escalation step vs creating another step with 0 minutes as interval.
