Displaying notifications about important account and contact events for user groups

would like to change the functionality for displaying notifications about important events described in the "Noteworthy event notifications" section of the academy documentation.

I would like to add a condition to the described functionality so that each notification is always displayed to a specific group of users, e.g., the system administrator, regardless of whether they are the record owner or not. They should receive every notification.

Is there a system setting or other parameter that regulates this?

If not, which process or function sends these notifications? Which function should be modified to add such a condition?
