How can I use custom trace channels defined in the editor settings?

Hey all, I believe this is a simple question but I can’t seem to find the answer anywhere.

I defined a custom trace channel in the editor settings for collision,
but I’m not sure how to reference it in my code.

My current code defines a term as ECC_MAX:


However, I’m not sure how to define it as my custom trace channel.

Is there a specific GameTraceChannel from 1-18 that my custom trace channel is?

Or is there some other way to reference my custom trace channel?

I am using version 4.8.2 for my project
