title: Don't See Back Button in createStackNavigator React Native
body: <p>I set up the <code>createStackNavigator</code> as follows:</p>
  <pre><code>export default function TabOneScreen() {
    return (
      &lt;NavigationContainer independent={true} &gt;
        &lt;Stack.Navigator initialRouteName=&quot;Screen1&quot;&gt;
          &lt;Stack.Screen name=&quot;Screen1&quot; component={Screen1} /&gt;
          &lt;Stack.Screen name=&quot;Screen2&quot; component={Screen2} /&gt;
        &lt;/Stack.Navigator&gt;
      &lt;/NavigationContainer&gt;
    );
  }
  </code></pre>
  <p>There is a button on <code>Screen1</code> that navigates to <code>Screen2</code>:</p>
  <pre><code>onPress={() =&gt; navigation.navigate('Screen2')}
  </code></pre>
  <p>However, when this navigates, <strong>I don't see the button to go back</strong> to <code>Screen1</code>. How do I enable this? Thanks!</p>
