Slick custom profile


Is there somewhere an example on how a Slick custom profile should look like ?
Context: I want to use streaming with Slick/Alpakka with Dremio. It’s a little bit of a weird system (they don’t publish the JDBC driver, by example, so you have to download it and provide it locally), but works pretty nice in certain cases, like replacement for Presto in AWS with data in S3.
I got it running with Doobie-> FS2-> Akka streams, but I would would love to have a Akka-only solution. And that implies, to my current understanding, writing a custom profile, generic JDBC has been removed. Or ?
