When reviewing the changelog of 0.5.9 I saw that this should be possible. I have installed the epic games launcher through Lutris, but it is not appearing as a source and I don’t see any options to do so. I have also installed dolphinEMU on my machine and I do not see that appearing as a source as well as no obvious method to get it to appear. Can someone please help me get this setup?
I just figured it out, for any people who are looking at this in the future this is how:
Top Left Hamburger Menu > Preferences > Services
From here just enable Dolphin and Epic Games.
