Subfolder management in Controller folder

Phoenix Forum Questions / Help

I am planning make some static page so,
I am making 2 subfolder in controller like this :
frontend
backend

for frontend folder i make subfolder like this :
fe_landing

for backend folder i make subfolder like this :
be_landing

for fe_landing folder i make file like this :
home.html.heex
about.html.heex
service.html.heex
contact.html.heex

for be_landing folder i make file like this :
home_controller.ex
home_html.ex
about_controller.ex
about_html.ex
service_controller.ex
service_html.ex
contact_controller.ex
contact_html.ex

in my home_controller.ex i code like this :

defmodule MyappWeb.Backend.BeLanding do  
use MyappWeb, :controller
  def home(conn, _params) do
   render(conn, :home, layout: false)  
  end
 end

in my home_html.ex i code like this :

defmodule MyappWeb.HomeHTML do
  use MyappWeb, :html
  embed_templates "../../frontend/fe_landing/*"
 end

in my router.ex i code like this :

  scope "/", MyappWeb do
    pipe_through :browser

    get "/fe_landing", HomeController, :home
  end

when to running this app, showing error like this :

Phoenix.Router.NoRouteError at GET /

no route found for GET / (Myapp.Router)

i would like to change the default page_controller.ex and page_html.ex is to subfolder controller → backend → be_landing home_controller.ex and home_html.ex, i mean i don’t want to use that page_controller.ex and page_html.ex
how to solved that

for at this time, my folder structure is correct, but i don’t know to route the file home.html.heex in subfolder controller → backend → be_landing to become default main page when users access for the first time

for the temporary solution i’ve found just make the file page_controller.ex and page_html.ex is the main page, and when users try access about page and want to go back homepage just go automatically into page.html.heex

this is the code i solved by my self but not sure, perhaps dear all you have some suggestion

for now, in my route like this

  scope "/", MyappWeb do
    pipe_through :browser

    get "/", PageController, :index
  end

  scope "/", MyappWeb do
    pipe_through :browser

    get "/home", HomeController, :home
    get "/about", HomeController, :about
    get "/jobs", HomeController, :jobs
    get "/pricing", HomeController, :pricing
    get "/products", HomeController, :products
  end

update
I just remove the PageController, :index then edit the “/home”, HomeController, :home become “/”, HomeController, :home
