How do I look up contents of a Complaint ID against me?

Another seller has put a Trademark Infringement complaint against me, but after emailing them, and reading all the documentation / emails from Amazon, I can’t find a reference to any specific word or image that is trademarked.

Someone said I can look up the Complaint ID filed against me, to see exactly what Trademark # they are referring to, so I can take action steps to correct it (if need be).

However I can’t find anywhere where I can input the Complaint ID to get more details.

I’ve checked the Performance Notifications page, but there are only things from 2021, nothing recent.
