ACM Notifications for expiring certificates

Customer wants an internal team to be notified when a certificate is approaching expiration so that they can respond and investigate the issue.

The plan is to issue public certs with auto-renewal configured so the primary goal is to get notified if that auto-renewal process is failing but a customer can accomplish that by simply getting a notification if the cert is less than 60 days from expiring, since AWS will auto-renew before the 60 day expiration timer. What are the available options to do this in AWS ?
