Lutris not showing as a source

Hello. I just installed Lutris for the first time. From the tutorials I’ve seen, Lutris should be available as a source under “sources”. I went to preferences to try to enable it, but couldn’t find it anywhere. I am just trying to look at the games the Lutris library has to offer. Any help is appreciated!

Not there in 0.5.17 - seems to have been removed??? no idea why
