Hello. I'm trying to disable the automatic sending of emails to customers when creating a helpdesk ticket, although it would be better if you can opt out of sending emails to the customer at any time.

I have tried disabling Default in Settings -> Technician -> Messages -> Subtype -> "Created Ticket". Set the "calendar.block_mail" parameter to true. Disable the scheduled action of Mail: Email queue manager, Timesheet: Reminder via email for employees and managers, and I can't get the emails to stop being sent.

What other alternatives do I have to disable this action? preferably one that doesn't require entering code, since at the moment we don't have access to the git repository.

Thanks and happy day.
