Not able to use the LiveUpdate Capacitor plugin for self hosted services | Capacitor Live Update Plugins

I have a Vue.js-based application and I am using Capacitor to build the mobile app.

The mobile application is working fine as expected but I am facing an issue with using the live-update plugin using self-hosted not capawesome cloud.
I have read the documentation from here

To get the latest version, I have the following file on my self-hosted server

app-versions.php

<?php
header('Access-Control-Allow-Origin: *'); 
header("Access-Control-Allow-Credentials: true");
header('Access-Control-Allow-Methods: GET, PUT, POST, DELETE, OPTIONS');
header('Access-Control-Max-Age: 1000');
header('Access-Control-Allow-Headers: Origin, Content-Type, X-Auth-Token , Authorization');

$data = [
    ["version" => "8.1.27"],
    ["version" => "8.1.28"],
];
header('Content-type: application/json');
echo json_encode($data);
?>

based on this, I have the following code in my main.js

import { LiveUpdate } from '@capawesome/capacitor-live-update';

const getBundleInfo = async () => {
    try {
        const request = await fetch("https://example.com/app-versions.php", {
            method: "GET",
            headers: {
              "Content-Type": "application/json",
              "Accept": "application/json",  
            }
        })
        const result = await request.json();
        let appVersion = version;
        if (result.length > 0) {
            appVersion = result[result.length - 1].version
            alert("Latest version is: " + appVersion)
        }
        return appVersion;
        
    } catch (error) {
        alert(error)
    }
}

(async () => {
    if (Capacitor.isNativePlatform()) {
        try {
            const result = await LiveUpdate.getCurrentBundle();
            // this result is always {bundleId: null}
        } catch (error) {
            alert(error)
        }

        try {
            const version = await getBundleInfo();
            await LiveUpdate.downloadBundle({
                url: `https://example.com/build-v${version}.zip`,
                bundleId: version,
            });
            await LiveUpdate.ready();
            await LiveUpdate.reload();
        } catch (error) {
            alert(error)
        }
    }
})();

Issues:-

• The LiveUpdate.getCurrentBundle(); always returns {bundleId: null} for self-hosted.
• If I call the setBundle() then it always says “LiveUpdate.setBundle() is not implemented on ios”.
  
• It is very difficult to know when should I download the new bundle because the applied bundle is always null.
• I rely on the exception of the downloadBundle function so when I get the error “Bundle already exists” my further script didn’t execute(i.e ready, reload).
