SLA Warning and breach notifications are not part of the activity logs on the parent recordIssue SLA Warning and breach notifications are not part of the activity logs on the parent record(ex:incident)CauseThis is the expected behaviour because the sla warning and breach notifications are created on task_sla table and not on the incident table.Emails which has been created on incident table only will be shown in the activity logs of incident and not from other tables like task_sla, etc.ResolutionIt would be technically possible through custom implementation where you can try to populate some work note update on the incident record whenever it's associated task sla warning/breach events/emails are created.
