Not able access the application running with skaffold and docker desktop on WSL 2

By default, skaffold dev only port-forwards user-defined port-forwards, those that are explicitly defined in the skaffold.yaml. For example:

portForward:
- resourceType: deployment
  resourceName: accounts-backend-deployment
  port: 5000
  localPort: 8080

You can use skaffold dev --port-forward=user,services to also port-forward services as well as any user-defined port-forwards.

Skaffold port-forwarding does not include ingress: that's currently cluster-specific. For example, with minikube, you'll need to run minikube tunnel separately, or alternatively minikube service -n ingress-nginx --url ingress-nginx-controller if using nginx-ingress.
