Custom claim access is missing from the Unity SDK as of v6.6 (Nov 2019). You can add a server function that returns the custom claims for the current user:

// Either use an existing User ID
UserRecord user = await FBAuth.GetUserAsync (uid);
return user.CustomClaims; // user.CustomClaims ["userNumber"]

// OR use a verified ID token
FirebaseToken token = await FBAuth.VerifyIdTokenAsync (idToken);
return token.Claims; // token.Claims ["userNumber"]

Important: If you use a billed-usage server, like Cloud Functions, this approach will incur billing charges, unlike a built-in Firebase method.

Other platforms (Android, iOS, web) have this method already (getIdTokenResult), so I submitted a feature request to Firebase to include it in a future version.
