I'm newbie and I need help to set up some particular Tasks in Jira Service management

[Eduardo Siuse]

1. How can I configure the display of the total number of tickets registered by users, does this refer to the display of the portal?

2. Is there a way to download the total number of tickets that were resolved with the information that each ticket has?

3. Is it possible to configure the sending of a notification email when a ticket is in progress? this email would be for someone who is not part of the technical support team or the user. To be more exact I would like to know if when I start working on a ticket I can notify another member of the company who is not part of the technical service team. I do not want to include him as part of the team because he would not have any activity during the resolution, it is only for information.
