How do I activate bell and email notification for a member I add to SR management ?

Summary:
hello,
how do I get notification to a member that I add in SR management even if they are not part of any queue?
Thanks

(in this screen I added Gianfranco Nero as a team member to manage the SR and would like him to get an email notification and a bell notification)
Thanks
Gianfranco
