How to setup ingress with ingress controller in a separate namespace for redmine in k8s?

Question

I am a tad new-ish to k8s and trying to set up Redmine on Amazon EKS cluster using Traefik. I lack a tad of understanding as to how the controller will pick up the ingress, especially given that the ingress is in the redmine namespace and the controller resides in it's own namespace. Below are my settings: Traefik Ingress Controller:

traefik:
  providers:
    kubernetesCRD:
      allowCrossNamespace: false
    kubernetesIngress:
      enabled: false

  logs:
    general:
      level: INFO
    access:
      enabled: true

  ports:
    web:
      redirectTo: websecure

  service:
    annotations:
      "service.beta.kubernetes.io/aws-load-balancer-type": nlb
      "service.beta.kubernetes.io/aws-load-balancer-ssl-cert": "aws-arn-id"
      "service.beta.kubernetes.io/aws-load-balancer-ssl-ports": "443"
    spec:
      externalTrafficPolicy: Local

  ingressRoute:
    dashboard:
      enabled: false

I disabled the ingress that came with the redmine config and created my own as I wanted traffic re-directed to https:

---
apiVersion: traefik.containo.us/v1alpha1
kind: Middleware
metadata:
  name: redirect-https
spec:
  redirectScheme:
    scheme: https
    permanent: true

---
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  annotations:
    kubernetes.io/ingress.class: traefik
    traefik.ingress.kubernetes.io/router.tls: "true"
    traefik.ingress.kubernetes.io/router.entrypoints: web, websecure
    traefik.ingress.kubernetes.io/router.middlewares: redmine-redirect-https@kubernetescrd
  name: redmine-ingress
  namespace: redmine
spec:
  rules:
    - host: redmine.mydomain.org
      http:
        paths:
          - backend:
              service:
                name: mydomain-redmine
                port:
                  number: 80
            path: /
            pathType: ImplementationSpecific

and my ingress and service deployment file config for Redmine:

redmine:
  fullnameOverride: "mydomain-redmine"

  service:
    type: LoadBalancer
    port: 80
    annotations: {}

  ingress:
    enabled: false

I know there's something amiss but not sure what that is right now. Any pointers will be appreciated.
