I emailed support and was given a link to this article rather than an answer to my Question. I play on Epic and my partner, who lives in the same house running on the same network, plays on Steam. Do clear, thorough instructions for setting up a Co-op cross platform game exist anywhere? I get the impression one of us has to create a server, How? And then there are launch commands for the server to set modes, what modes do I need? Why can't it be simple like Borderlands 3 and just choose LAN game.
