title: How does Electron determine application identity for requestSingleInstanceLock?
body: <p>We're trying to build our Electron app under a different name, with a different <code>appId</code> so that we can run it alongside our original app - but it always triggers Electrons <a href="https://www.electronjs.org/docs/api/app#event-second-instance" rel="nofollow noreferrer">'second-instance'</a> - at least on Windows where I'm testing.</p>
  
  <p>What do we need to do to make Electron that these are two entirely separate applications?</p>
