How to remove bottom taskbar on a certain screen in React Native?

I have added a chat to my app with react-native-gifted-chat and I want to remove the taskbar (tabBar) on the specific chat screen, to offer more space and a better user experience.

This happens on iOS and Android

But I can't hide it, despite trying different ways to do it:

• Add tabBarVisible: false,

• I have added my function

  const getTabBarVisibility = (route) => { const routeName = route.state ? route.state.routes [route.state.index] .name : '';

   if (routeName === 'Chat') {
     return false
   }
   return true
  

  }

• I have added react-navigation options: (https://github.com/react-navigation/react-navigation/issues/7677)

  const getTabBarVisible = (route) => { const routeName = route.state ? route.state.routes [route.state.index] .name : route.params? .screen || 'Home';

   if (routeName === 'Details') {
     return false;
   }
   return true;
  

  }

But I can't get tabBar to hide on this screen.

I show screenshots and the code I have tried to fix this:

const MessageStack = ({ navigation }) => (
  <Stack.Navigator>
    <Stack.Screen name="Messages" component={MensajeScreen} />
    <Stack.Screen
      name="Chat"
      component={ChatScreen}
      options={({ route }) => ({
        //tabBarVisible: route.state && route.state.index === 0,
        title: route.params.userName,
        headerBackTitleVisible: false,
        //tabBarVisible:false
      })}
    />
  </Stack.Navigator>
)

const ProfileStack = ({ navigation }) => (
  <Stack.Navigator>
    <Stack.Screen
      name="Profile"
      component={ProfileScreen}
      options={{
        headerShown: false,
      }}
    />
  </Stack.Navigator>
)

const AppStack = () => {

  const getTabBarVisible = (route) =>{
    const routeName = route.state
      ?  route.state.routes[route.state.index].name
      : route.params?.screen || 'Home';
  
    if (routeName === 'Details') {
      return false;
    }
    return true;
  }

  return (
    <Tab.Navigator
    screenOptions={{
      activeTintColor: '#2e64e5'
    }}>
      <Tab.Screen
        name="Home"
        component={FeedStack}
        options={({ route }) => ({
          tabBarLabel: 'Home',
          headerShown: false,
          tabBarVisible: route.state && route.state.index === 0,
          tabBarIcon: ({ color, size }) => (
            <MaterialCommunityIcons
              name="home-outline"
              color={color}
              size={size}
            />
          ),
        })}
      />
      <Tab.Screen
        name="Messages"
        component={MessageStack}
        options={({ route }) => ({
          tabBarVisible: getTabBarVisible(route),
          //tabBarVisible:false,
          //tabBarVisible: getTabBarVisibility(route),
          tabBarVisible: route.state && route.state.index === 0,
          headerShown: false,
          tabBarIcon: ({ color, size }) => (
            <Ionicons
              name="chatbox-ellipses-outline"
              color={color}
              size={size}
            />
          ),
        })}
      />
      <Tab.Screen
        name="Profile"
        component={ProfileStack}
        options={{
          headerShown: false,
          tabBarIcon: ({ color, size }) => (
            <Ionicons name="person-outline" color={color} size={size} />
          ),
