Hello @sayyam_6772
Yes, Had used this extension called Web Vitals which is easy to install and configure.
To make this extension works, Add the right event in your rule to track the Web vitals metrics and add the data element in your rule to retrieve data about Web Vital metrics like name, ID, etc..
Particular on your query to reduce bounce rate, there are other metrics like LCP / CLS / need to meet with their threshold. Once you achieve it that will helps to reduce bounce rate.
Now how to improve LCP / CLS / FID? This like might help you https://web.dev/optimize-lcp/ whish shows step by step action and areas to improve on your web application.
