We had a great flight to EDI on Delta One (first time) and slept well

I'm having difficulty figuring out if there is any J lounge, or any [nice?] lounge at all in EDI for Delta One passengers.
We also have Amex Plat/Priority Pass, if that helps in this situation.

We don't have a sense of the size of the EDI departure area, although the arrivals area/baggage claim wasn't all that large.e

A comfortable place to wait would be especially nice, given that a few years ago, we decided to try to minimize one potential source of stress by arriving nice an early at the airport. No more worries about "what if there's bad traffic", or "what if TSA is all backed up" or any such delay, etc. Obviously, this typically gives us lots of extra time to "enjoy" the airports

Thanks for any suggestions.
