how to trigger chrome extension function from puppeteer Cluster - google-chrome-extension

Question

I need to trigger a function in background.js in extension from puppeteer Cluster
here is my code :
const wait = (ms) => new Promise(resolve => setTimeout(resolve, ms));
(async () => {
const puppeteer = addExtra(puppeteerStream);
const pathToExtension = "C:/Users/Proj/test-extension";
const extensionId = 'lpnlgnlkloegindjk443sfdbjipo';
const cluster = await Cluster.launch({
concurrency: Cluster.CONCURRENCY_PAGE,
maxConcurrency: 50,
timeout: 86400000,
retryLimit: 10,
retryDelay: 1000,
puppeteer: puppeteer,
executablePath: executablePath(),
puppeteerOptions: {
executablePath: "C:/Program Files/Google/Chrome/Application/chrome.exe",
timeout: 120000,
headless: false,
pipe: true,
defaultViewport:null,
ignoreDefaultArgs: [
],
args: ["--no-sandbox", "--disable-setuid-sandbox", "--disable-notifications", "--allow-http-screen-capture", "--autoplay-policy=no-user-gesture-required",
'--disable-gpu',
'--disable-dev-shm-usage',
'--no-first-run',
'--enable-usermedia-screen-capturing',
'--auto-select-desktop-capture-source=pickme',
'--no-zygote',
`--whitelisted-extension-id=${extensionId}`,
'--enable-remote-extensions',
'--start-maximized',
`--disable-extensions-except=${pathToExtension}`,
`--load-extension=${pathToExtension}`,
]
}
});
// setup the function to be executed for each request
cluster.task(async ({ page, data: url }) => {
return start(page, url);
});
app.get('/', async function (req, res) {
res.send("index page");
});
app.get('/start', async function (req, res) { // expects URL to be given by ?url=...
try {
// run the task function for the URL
const resp = cluster.queue(req.query.url);
res.send(resp);
} catch (err) {
res.end('Error: ' + err.message);
}
});
async function start(page, Url) {
const context = page.browser().defaultBrowserContext();
await page.goto(Url);
}
})();
now I can run mt puppeteer and click a button in my extension manually but what I need is call the function (same as button click in extension) from puppeteer cluster automatically after await page.goto(Url);
I can do that when I'm using puppeteer without cluster like :
const browser = await puppeteer.launch({
headless: false,
args: [
`--whitelisted-extension-id=${extensionId}`,
'--no-sandbox',
'--disable-setuid-sandbox',
'--disable-dev-shm-usage',
`--disable-extensions-except=${pathToExtension}`,
`--load-extension=${pathToExtension}`,
],
});
const page = await browser.newPage();
await page.goto('https://www.youtube.com/', { waitUntil: 'networkidle2' });
const targets = await browser.targets();
const backgroundPageTarget = targets.find(target => target.type() === 'background_page' && target.url().startsWith(`chrome-extension://${extensionId}/`));
const backgroundPage = await backgroundPageTarget.page();
backgroundPage.on('console', msg => {
for (let i = 0; i < msg.args().length; i++) {
console.log(`${i}: ${msg.args()[i]}`);
}
});
await backgroundPage.evaluate(() => {
startFunction();
return Promise.resolve(42);
});
But I cannot get the targets in cluster any suggestion
