Automated email/teams notification if SLA is not met

I have a published dashboard with the number of tickets in the row with their id number and then in the columns is shows the age of the ticket. I have kept certain color codes for the age such as 0-3 days, 3 to 6 days and 6+ days. All tickets are also having another column with the names of the ticket owners or user list. All the members in the team are given with the subscription at 7 am in the morning. 

But I want them to get notifications in outlook/teams if their cases are outside the SLA. Example if John has got 3 tickets with the current age is 6 for all of them. The he shall get a automated notification with the list of these 3 cases.
