Laravel metrics can't be generated

Describe your environment

We are encountering an issue when trying to implement OTEL on our Laravel app, and we are trying to get the traces and metrics from our app using auto instrumentation. The traces part works fine, but the metrics seem to be empty or not working

Are metrics being tracked for Laravel? if yes: how can we debug this?
If not, what are the options we have for metrics? we want to get "All requests" count / duration / status code

Below are the details of our conditions.

Environment:

PHP version: 8.1.28
Laravel version: 10
Otel Collector version: 0.100.0
Hosted on AWS EKS

We are using these OTEL packages

"open-telemetry/detector-container": "^1.0",
"open-telemetry/exporter-otlp": "^1.0",
"open-telemetry/gen-otlp-protobuf": "^1.1",
"open-telemetry/opentelemetry-auto-guzzle": "^1.0",
"open-telemetry/opentelemetry-auto-laravel": "^0.0.26",
"open-telemetry/sdk": "^1.0",
"open-telemetry/transport-grpc": "^1.0",
"open-telemetry/api":"^1.0"

Environment variables on our app

OTEL_EXPORTER_OTLP_ENDPOINT=http://otel-collector:4317
OTEL_SERVICE_NAME=app
OTEL_PHP_AUTOLOAD_ENABLED=true;
OTEL_TRACES_EXPORTER=otlp;

Steps to reproduce deploy Laravel app using the given details

What is the expected behavior? I can find the metrics on Prometheus https://opentelemetry.io/docs/specs/semconv/http/http-metrics/
