Chromium browser with PM2 cluster mode

[Aditya]

On VPS I have installed chromium browser and given executable path like this:

const browser = await puppeteer.launch({

executablePath: '/usr/bin/chromium-browser'

})

Reference link: https://stackoverflow.com/a/63137427

But it is mentioned here: https://stackoverflow.com/a/57663436 that path should be different for each cluster in PM2. With 5 PM2 instance cluster how can I give different executable paths so that load gets shared among each cluster? Any suggestions?
