Edit text notification on icon bell

Hi to all,

we have to customize notifications related to career development page. I'm referring to the notifications that manager and employee received when manager or HR suggest or delete a suggested role to the employee.

We have to modify all the component of the notification. So, we need to change the text inside the icon bell, and the text of the notification.

Can you tell me where I can find and modify this notification? Do I use alert composer or analytics?

How can I customize the text inside the icon bell?

Thanks,

Imma.
