I have a problem with navigation jetpack compose, the problem is when I run the app on my phone, there is no screen just an empty screen but if I do a long click inside the empty screen after the long click the screen that I put in navigation display.

what is the problem and how can I fix it?

package com.example.navigationappfirst

import android.os.Bundle
import androidx.activity.ComponentActivity
import androidx.activity.compose.setContent
import androidx.navigation.compose.NavHost
import androidx.navigation.compose.composable
import androidx.navigation.compose.rememberNavController
import com.example.navigationappfirst.ui.theme.NavigationAppFirstTheme

class MainActivity : ComponentActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContent {
            NavigationAppFirstTheme {
                val navController = rememberNavController()
                NavHost(navController = navController, startDestination = "younes1") {
                    composable(route = "younes1") {
                        NoteScreen(text = "younes1", navController)
                    }
                    composable(route = "younes2") {
                        NoteScreen(text = "younes2", navController)
                    }

                }
            }
        }
    }
}
