REQUEST_IGNORE_BATTERY_OPTIMIZATIONS how to do it right

I have IntentService task in foreground mode, but in Android M+ the task stops in Doze mode. I read Google banned if the app uses intent to set themselves in whitelist. But if I use permission and check GRANT or DENIED, I get the granted result, but nothing happen. I don't see my app in whitelist. How can I add the app in whitelist without banned? (I added permission in AndroidManifest.xml)

if(Build.VERSION.SDK_INT>=23){
    int permissionCheck= ContextCompat
                    .checkSelfPermission(this, Manifest.permission.REQUEST_IGNORE_BATTERY_OPTIMIZATIONS);

    if(permissionCheck == PackageManager.PERMISSION_DENIED){

        //Should we show an explanation
        if(ActivityCompat.shouldShowRequestPermissionRationale(this, Manifest.permission.REQUEST_IGNORE_BATTERY_OPTIMIZATIONS)){
            //Show an explanation
            final String message = "";
             Snackbar.make(coordinatorLayoutView,message,Snackbar.LENGTH_LONG)
                     .setAction("GRANT", new View.OnClickListener() {
                         @Override
                         public void onClick(View v) {
                             ActivityCompat.requestPermissions(MainActivity.this, new String[]{ Manifest.permission.REQUEST_IGNORE_BATTERY_OPTIMIZATIONS }, PERMISSION_REQUEST_CODE);
                         }
                     })
                     .show();

                }else{
                    //No explanation need,we can request the permission
                    ActivityCompat.requestPermissions(this, new String[]{ Manifest.permission.REQUEST_IGNORE_BATTERY_OPTIMIZATIONS }, PERMISSION_REQUEST_CODE);
                }
            }
        }
