Remove underscore from notification trigger name

Summary:

I've created notification triggers under HR Help Desk Request on the Message Child Object to be triggered when the agent/customer responses (sends message) on the HR Help Desk SR.

However, when the bell notification triggers the name of the notification includes underscores in the name.

Is there a way to remove this? I have the same issue with a milestone child object notification trigger.
