NWS Alerts integration

I've been messing with this integration for the better part of 3 days now and I can't seem to figure out how to create a card with the actual alert text. I've tried the example in github and reddit posts. I've seen people use it so I have no doubt it's me and not the integration, but I'm stumped. I feel like I'm missing a step that's not document out there. I've tried markdown and custom cards and they all either error or display no text. Can someone break it down for me in simple steps? Thanks in advance!
