Following this documentation: https://www.elastic.co/guide/en/kibana/master/alert-management.html
It appears in the alerts page you can edit custom alerts you have made, but alerts made for APM would need to be edited in the APM module. Inside the APM module I only see the ability to add a new alert and not edit or even see any existing alerts. Am I missing something obvious, or is editing existing APM alerts not possible at the moment?
