Changing the content of notifications heading

Content (required):

Hello,

One of the clients has the approval workflow as show below for Learning Request:

Employee raises request => Line Manager => Learning Specialist

They have a requirement when the line manager and learning specialist are the same, it should show on the notifications heading (when they access the list on the bell icon) that they have to approve a particular notification as a line manager and the next one maybe as a learning specialist. How can the notifications heading be changed to reflect this?

Thanks,

Mohnish
