I want to create Level 1 and Level 2 queues in Jira Service Management. Whenever a request related to L1 support comes in, it should be displayed in the Level 1 queue. If the issue is not resolved by Level 1, I want it to be escalated automatically to the Level 2 queue escalated automatically to the Level 2 queue and notify the Level 2 support executives.How can I set this up in Jira Service Management ?
