Kotlin Options menu not displaying on

so I've implemented a simple Kotlin program for displaying the options menu and ran it on like every type of emulator, the output does not display the options menu instead it only displays the contents of the activity_main.xml file. here's the entire app code :

activity_main.xml :-

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">


    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Main Activity"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent" />

</androidx.constraintlayout.widget.ConstraintLayout>

res/menu/data_items.xml :-

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto">

    <item
        android:id="@+id/save"
        android:title="SAVE"
        android:icon="@android:drawable/ic_menu_save"
        app:showAsAction="never"/>

    <item
        android:id="@+id/camera"
        android:title="CAMERA"
        android:icon="@android:drawable/ic_menu_camera"
        app:showAsAction="never"/>

    <item
        android:id="@+id/edit"
        android:title="EDIT"
        android:icon="@android:drawable/ic_menu_edit"
        app:showAsAction="never"/>
</menu>

MainActivity.kt :-

package com.yash.menudesigning

import androidx.appcompat.app.AppCompatActivity
import android.os.Bundle
import android.view.Menu

class MainActivity : AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
    }

    override fun onCreateOptionsMenu(menu: Menu): Boolean {
        menuInflater.inflate(R.menu.data_items,menu)
        return true
    }
}

res/values/themes.xml

<resources xmlns:tools="http://schemas.android.com/tools">
    <!-- Base application theme. -->
    <style name="Base.Theme.MenuDesigning" parent="Theme.Material3.DayNight.NoActionBar">
        <!-- Customize your light theme here. -->
        <!-- <item name="colorPrimary">@color/my_light_primary</item> -->
    </style>

    <style name="Theme.MenuDesigning" parent="Base.Theme.MenuDesigning" />
</resources>

result :- (image)

I've tried running it on both Virtual and Physical devices, also tried different API versions, also checked for errors, cleaned the code, rebuilded, still the output remains the same.

expected Output :-

is anything wrong with my Android Studio? please guide me

Try changing the style. You want to see the menu in the ActionBar but are defining a style with a non action bar theme (Theme.Material3.DayNight.NoActionBar)
