[2020] Multiplayer Issues

So my brother and I just saw that Deep Rock came to game pass and as we both have the game pass, we were very excited to finally play this game together. However, upon installing and loading up the game we could not figure out how to join each other's games. We each took turns trying to host servers, both public and private, but could not seem to find each other anywhere and the Xbox overlay on windows 10 would not allow us to simply invite. If anyone has any ideas of what we could be doing wrong, please help!! We want to be badass space Dwarves together so bad!!
