How to create SearchView in appbar without extra button

Question

I want to create a SearchView in my second activity. When I tap on the button search in my first activity I must go to the second activity and the Searchview must work there immediately without extra button for start it. I want my secondary activity to look like

I tried different examples but all of them start searchview by extra button search. The main problem - how to create such view in my appbar to write a request of search immediately

My code: MainActivity

public class MainActivity extends AppCompatActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Objects.requireNonNull(getSupportActionBar()).setDisplayShowTitleEnabled(false);
    }
    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        MenuInflater inflater = getMenuInflater();
        inflater.inflate(R.menu.main_menu, menu);
        return true;
    }
    @Override
    public boolean onOptionsItemSelected(@NonNull MenuItem item) {
        Intent intent = new Intent(MainActivity.this,SearchableActivity.class);
        startActivity(intent);
        return super.onOptionsItemSelected(item);
    }
}  

SearchableActivity

public class SearchableActivity extends AppCompatActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_searchable);
    }
    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the options menu from XML
        MenuInflater inflater = getMenuInflater();
        inflater.inflate(R.menu.search_menu, menu);
        MenuItem searchItem = menu.findItem(R.id.search_button);
       return true;
    }
}

menu for the first activity

<?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/action_search_note"
        android:icon="@drawable/ic_baseline_search_24"
        android:title="@string/search_main_icon"
        app:showAsAction="always"/>
</menu>

menu for the second activity

<?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/search_button"
        android:icon="@drawable/ic_baseline_send_24"
        android:title="search_button"
        app:showAsAction="ifRoom|collapseActionView"
        app:actionViewClass="androidx.appcompat.widget.SearchView"/>
</menu>
