Unable to open traefik and service dashboard at subdirectory level

Traefik Traefik v2
,
#1

Below is a part of my config file. I can access the traefik dashboard at https://traefik.subdomain.domain and prometheus page at https://prometheus.subdomain.domain

However I want to access these pages at at subdirectory level, and not subdomain.
Something like:

https://subdomain.domain/traefik to get to traefik dashboard
https://subdomain.domain/prometheus to get to prometheus dashboard

I tried with "traefik.http.routers.traefik.rule=Host(`subdomain.domain`) && PathPrefix(`/traefik`)" to only get a 404 Page not found

version: '3'

services:
  traefik:
    image: traefik:v2.0
    command: 
      - --entryPoints.http.address=:80
      - --entryPoints.https.address=:443
      - --providers.docker.exposedByDefault=false
      - --accesslog=true 

    ports:
      - "80:80"
      - "443:443"
      - "8080:8080"
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock   
      - ./traefik/traefik.toml:/etc/traefik/traefik.toml
      - ./traefik/traefik.config.toml:/etc/traefik/traefik.config.toml
      - ./certs:/etc/certs
    labels:
      - "traefik.http.routers.traefik.rule=Host(`traefik.subdomain.domain}`)"
      - "traefik.http.routers.traefik.service=api@internal"
      - "traefik.http.routers.traefik.entrypoints=https"
      - "traefik.http.routers.traefik.tls=true"

  prometheus:
    image: prom/prometheus:latest
    ports:
      - 9090:9090
    command:
      - --config.file=/etc/prometheus/prometheus.yml
      - --web.enable-lifecycle
    labels:
      - "traefik.enable=true"    
      - "traefik.http.routers.prometheus.rule=Host(`prometheus.subdomain.domain`)"
      - "traefik.http.routers.prometheus.entrypoints=https"
      - "traefik.http.routers.prometheus.tls=true"

Appreciate the help.

I tried this for prometheus with url pointing to subdomain.domain/prometheus/, with no luck. The webpage gets redirected to /graph and then 404

- "traefik.http.routers.prometheus.rule=Host(`subdomain.domain`) && PathPrefix(`/prometheus/`)"
- "traefik.http.routers.prometheus.middlewares=prometheus-stripprefix"
- "traefik.http.middlewares.prometheus-stripprefix.stripprefix.prefixes=/prometheus"

It's not gonna work if the underlying app does not support it. For traefik dashboard there is an issue here:https://github.com/containous/traefik/issues/5853 but as far as prometheus goes, if it does not support it, it's impossible.

Thanks Idez, it works as expected. On the same lines, do you know how this can be done for Grafana?
