Need help making dialogue for Cutscene Editor

I’ve looked around over the past three days while I’ve been making a cutscene to attach to the actual custom level I’m working on, but I’m struggling to find much in the way of getting a clear answer.
I’d like to give it the same dialogue text box as when a character talks in the campaign cutscenes that shows up at the bottom left of the screen, but I’m getting no luck searching. Everything’s more or less set besides that and figuring out how to change Actor Decals in cutscenes, but having a text dialogue is what I’m after first and foremost.

Edit - nvm, i give up
