Microsoft Graph Event Extensions

Question

Hello,

I am creating an application that sends reminder emails to the attendees of appointments. I have a template HTML email that I fill in the name of the attendees when sending the email. This does not work for all appointments, as some of the appointments are with children. My client wants to send a differently worded email to the parents of the child which includes the child and the parent's name.

I need some special data stored in each event so that the code can determine if an appointment is for a child or a parent, and send the correct emails with the correct information. I thought that there was an event "notes" section that I could have used, but it turns out that there is no such thing.

My next idea is to use event extensions, but recurring events do not share extensions. Is there a way to make recurring events share some data? I am hoping to avoid using a third-party like a database since the outlook calendar serves as the database for all information in this scheduling application.

If anyone has any guidance for me, whether an even better solution for this specific problem or some tips on extensions, it would be much appreciated.
