Is Steam overlay possible with the current Electron version?

app.commandLine.appendSwitch('in-process-gpu')
app.commandLine.appendSwitch('disable-direct-composition')

I don't see these in the Electron documentation.

What exactly you don't see? AFAIK these command line arguments are not specific to electron, they are for the chrome.
Steamworks.js works in any version of electron above 12.

Oh, that explains it, then. I was looking for them in Electron documentation. Anyway, now I've tested it and it works. Thanks for your help.
