Hello,
I am working with the OSTicket system and I would like to understand the email notification process that occurs when a ticket is created. Specifically, I am looking to identify the following:

Which email notifications are triggered when a ticket is created? (e.g., confirmation email to the user, notification to the assigned agent, etc.)
Are these notifications handled by specific functions or methods in the source code? If yes, could you please point me to the relevant methods or files?

I am particularly interested in understanding which parts of the system (e.g., classes or methods) are responsible for sending the emails when a ticket is created. Any guidance or insights on this would be very helpful.
