LG WebOS 3.0 TV App Exit Button Close App and

I am developing a TV app for LG 4K TVs in webOS 3.0.

self_evaluation_checklist_3.4.xlsx lists a requirement for Exit button behavior as below.

"For webOS 3.0, pressing the EXIT button the app is completely closed and does not remain on the Recent list."

I have been searching but I haven't had any luck finding the API call to close the app completely and also removes the app from the Recent list.

All I could find is webOS.platformBack(); but that only takes back to the Home screen of the TV and doesn't close the app.

How can I close the app completely and don't list the app in the Recent list?

To exit the app and leave it in the Recent list I used the following:

const APPLICATION_MANAGER_SERVICE = 'luna://com.webos.applicationManager';
const TV_APP_ID = 'com.webos.app.livetv';

function sendAppToBackground() {
  webOS.service.request(APPLICATION_MANAGER_SERVICE, {
    method: 'launch',
    parameters: { id: TV_APP_ID },
    onSuccess(response) {
      if (response.returnValue === false) {
        console.error(`Error sending Application to background and bringing TV Application with ID ${TV_APP_ID} to the foreground.`);
        forciblyExitApp();
      }
    },
    onFailure(error) {
      console.error(error);
      forciblyExitApp();
    },
  });
}

function forciblyExitApp() {
  window.close();
}

This is correct method ( webOS.platformBack(); ). At least our app uses the same method for all 3 generations of WebOS and has never been declined by LG QA Center for this.
