title: Firebase Realtime Database Issue
body: <p>I am attempting to access the firebase realtime database using the example provided on the firebase <a href="https://firebase.google.com/docs/database/unity/save-data" rel="nofollow noreferrer">documentation</a>.</p>
  <pre><code>FirebaseApp.DefaultInstance.SetEditorDatabaseUrl(&quot;https://YOUR-FIREBASE-APP.firebaseio.com/&quot;);
  
  DatabaseReference reference = FirebaseDatabase.DefaultInstance.RootReference;
  </code></pre>
  <p>However, I am noticing that the references are not being recognized and the following errors are generating:</p>
  <blockquote>
  <p>error CS1061: 'FirebaseApp' does not contain a definition for 'SetEditorDatabaseUrl' and no accessible extension method 'SetEditorDatabaseUrl' accepting a first argument of type 'FirebaseApp' could be found (are you missing a using directive or an assembly reference?)</p>
  </blockquote>
  <blockquote>
  <p>error CS0234: The type or namespace name 'Editor' does not exist in the namespace 'Firebase.Unity' (are you missing an assembly reference?)</p>
  </blockquote>
  <p>Below is the code that I am using. As you can see, I am referencing the Firebase and Firebase.Database.</p>
  <pre><code>using System;
  using Firebase;
  using Firebase.Database;
  using UnityEngine;
  
  public class OnetoOneChat : MonoBehaviour
  {
      private DatabaseReference reference;
  
      private void Start()
      {
         FirebaseApp.DefaultInstance.SetEditorDatabaseUrl(&quot;databaseURL&quot;);
         reference = FirebaseDatabase.DefaultInstance.RootReference;
      }
  
      private void SendMessage()
      {
  
      }
  
      private void ListenForMessages()
      {
  
      }
  }
  </code></pre>
  <p>These files are located in the package folder of my unity project: I am not sure what is the issue. Any insight on how I can resolve this issue will be greatly appreciated.</p>
