Request for Assistance: Adding DOB Field and Birthday Automation in Contacts Module

I would like to add a Date of Birth (DOB) field to the Contacts module form. The goal is to have each contact’s birthday recorded so I can be notified either on the day or a day in advance through a reminder or notification. This will help ensure that no special day is missed.

Additionally, I’m looking to set up an automation that sends out a personalized birthday message or email.

Could you kindly guide me through the step-by-step process to implement this functionality?
