Can someone help me figure out how to set up a trigger to send an email notification to the requester when the requester is an agent; they mention another agent in their ticket; and that agent responds via email, which creates a private reply? We don't want end-users to see private replies, so I understand the default functionality, but when the requester is an agent who can see the private replies anyways, it would be nice if they were notified of the update.

If your main goal is to notify agents (who are requester of the ticket) about a private comment, this can be done by adding the agent manually as a follower on the ticket.
In addition, you can also use a trigger that will have a condition to send a notification to a requester if the requester is an agent. Please refer to the screenshot below. Take note that all of your agents that request tickets should be added under "Meet ANY of the following conditions" to make sure that it will fire for all agents that have requested a ticket.
