Laravel Function for Auto Booking Denial

Create a function in my laravel 8 website. My website is a portal that connects car rental companies with drivers to transfer cars between cities. Car rental companies have cars that they need back to their city from other locations. They create an ad and drivers can send a booking request. The car rental company then get an email with option to accept or deny the booking based on the pick up time and comment the driver send in the request. The problem is that if many people send booking requests on the same ad, but the car company accept one and ignore all other bookings. Then the other bookings do not get a booking denied notification. So the function has to automatically send a booking denied notification email to all other drivers when a booking is confirmed and the car rental company has not answered/denied the booking. The denied booking email is already created for one the car company choose to deny, so the same email can be used for the automatic sending. The website is built in laravel 8. I am a react developer myself, but don’t want to use time to learn PHP at the moment. As a developer I know this is an easy fix.
