I created a program without an icon that runs the service by pressing the foreground button and the music is played, but our program is not hidden. It is possible to help

source code frome
MainActivity.java

    public class MainActivity extends AppCompatActivity {
    
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);
            Intent servIntent = new Intent(this, service.class);
            Button start =(Button) findViewById(R.id.start);
            Button stop =(Button) findViewById(R.id.stop);
            Button hide =(Button) findViewById(R.id.hide);
            start.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View view) {
                    //for start foreground service
                    ContextCompat.startForegroundService(MainActivity.this, servIntent);
    
                }
            });
            stop.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View view) {
                    //for stop service
    Intent intent =new Intent(MainActivity.this,service.class);
    stopService(intent);
                }
            });
            hide.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View view) {
                    //for hide app
                    PackageManager packageManager=getPackageManager();
                    ComponentName componentName=new ComponentName(MainActivity.this,MainActivity.class);
                    packageManager.setComponentEnabledSetting(componentName,PackageManager.COMPONENT_ENABLED_STATE_DISABLED,PackageManager.DONT_KILL_APP);
                    Toast.makeText(getApplicationContext(), "app hide ", Toast.LENGTH_SHORT).show();
                }
            });
    
        }
    }

Part packageManager is about hiding the program icon
