Making public a WebApp

Hi!

We just developed a WebApp in Dataiku, and are trying to make it public, to set it as an applicative frontend.

Here, the documentation mentions that to do so, we should go to 'Administration > Settings > Login & Security, and add the “PROJECTKEY.webappId” in the authentication whitelist'. However, we cannot find the 'Authentication whitelist' option. Here is how the 'Administration > Settings > Login & Security' screen looks on our end:

Thanks!
