Trying to install selfHosted gitpod using k3s but no ingress present

kubectl describe svc proxy | grep -i ingress

i am using https://www.gitpod.io/docs/self-hosted/latest/installation/on-kubernetes instructions on this link . I have got all pods except load balancer not working. Also when i go to my domain just a 404 appears.
I am using k3s cluster on ubuntu os.
