Nginx Ingress not working for paths other than / - kubernetes-ingress

Question

I'm facing a very weird issue with Ingress Nginx. The Nginx was provisioned by RKE2 deployment as a daemonset (rke2-ingress-nginx-controller).
It works fine for any Ingress definition for which path points to / .
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
name: sealed-secrets-sealed-secrets-web
namespace: sealed-secrets
spec:
ingressClassName: nginx
rules:
- host: host.domain.com
http:
paths:
- backend:
service:
name: sealed-secrets-sealed-secrets-web
port:
number: 80
path: /
pathType: Prefix
But if instead of "/", the path points to something different (e.g. /sealed-secrets), I get an error 404 (not found), even if rewrite-target set.
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
name: sealed-secrets-sealed-secrets-web
namespace: sealed-secrets
spec:
ingressClassName: nginx
annotations:
nginx.ingress.kubernetes.io/rewrite-target: /
rules:
- host: host.domain.com
http:
paths:
- backend:
service:
name: sealed-secrets-sealed-secrets-web
port:
number: 80
path: /sealed-secrets
pathType: Prefix
I'm using sealed-secrets to illustrate, but the same happens for whatever ingress resource defined.
Any help will be appreciated.

It seems that I've missed the need for adding a regex to rewrite paths.
annotations:
nginx.ingress.kubernetes.io/ssl-redirect: 'false'
nginx.ingress.kubernetes.io/use-regex: "true"
nginx.ingress.kubernetes.io/rewrite-target: /$2
# -- Ingress hosts
hosts:
- host: host.domain.com
paths:
- path: /sealed-secrets(/|$)(.*)
pathType: Prefix
Now the connection is reaching the app and displaying the expected page.
