How to monitor Istio stats based on URI using prometheus?

We are using Istio 1.15.4 on EKS 1.23.6. Our application URL has customer id in it, for eg. https://neeleshgurjar.co.in/api/v1/customer_11

https://neeleshgurjar.co.in/api/v1/customer_12

All requests are landing on Istio Ingress Gateway i.e. AWS managed ALB.

Now how can I monitor the number of request for customer_11 and same for customer_12?

I want to monitor them using Prometheus - grafana stack.
