subdomain - Firebase hosting: Serve different pages from different custom domains

Question

We're using custom domains on firebase hosting: our app, served from index.html, runs nicely on app.example.com. We've also connected www.example.com, which serves the app as well.

The problem is: on www.example.com I want to be able to host a simple static page. Is there a way to configure this in the rewrites? We can easily output an extra html file in the deploy, next to index.html.

Any ideas?

Our firebase.json:

{
  "database": {
    "rules": "database.rules.json"
  },
  "hosting": {
    "public": "public",
    "rewrites": [
      {
        "source": "**",
        "destination": "/index.html"
      }
    ]
  }
}
