I created a user and logged in, using `<firebase-auth>` (with code snippet below) in the main element, but I can only retrieve the user's information in that main element (and not a child element).

```
    <firebase-auth
        id="auth"
        app-name="Carecollector"
        provider="google"
        signed-in="{{signedIn}}"
        user="{{user}}">
    </firebase-auth>

```

How do I retrieve information about the current user in a child element?
Should I create a `<firebase-auth>` element inside every other element that needs the current user information?
