title: How to configure a custom kiosk-enabled app from Google Admin (App Management)?
body: <p>I have some "Single app Chrome kiosk device management license" and I want to set a url remotely (from Google Admin) for each OU.</p>
  
  <p>When using Chrome Sign Builder, it is easy, there is a "configure" button :</p>

  <p>But now I built my App using Chrome App Builder and there is no way to have those "environment variables" through the json config file (the button "configure" is not there) :</p>

  <p>How to show this "configure" button?</p>
  
  <p>EDIT : <a href="https://support.google.com/chrome/a/answer/6137033?hl=en" rel="nofollow noreferrer">https://support.google.com/chrome/a/answer/6137033?hl=en</a> "If a Chrome app supports a config file, you can upload a config file to customize the app." -> So I guess It is definitely doable, but I can't find how</p>
  
  <p>EDIT 2:
  Admin Google did an interface update, so for those:
