Elixir issue with Bamboo.SentEmailViewerPlug - email

Question

I do have an issue with mentioned function. This is the error from browser:
function Bamboo.SentEmailViewerPlug.init/1 is undefined (module Bamboo.SentEmailViewerPlug is not available)
And this is from console :
[error] #PID<0.868.0> running RewardappWeb.Endpoint (connection #PID<0.829.0>, stream id 4) terminated
Server: localhost:4000 (http)
Request: GET /mailbox
** (exit) an exception was raised:
** (UndefinedFunctionError) function Bamboo.SentEmailViewerPlug.init/1 is undefined (module Bamboo.SentEmailViewerPlug is not available)

Here is my router.ex file :
defmodule RewardappWeb.Router do
use RewardappWeb, :router
use Phoenix.Router
pipeline :browser do
plug :accepts, ["html"]
plug :fetch_session
plug :fetch_live_flash
plug :put_root_layout, {RewardappWeb.LayoutView, :root}
plug :protect_from_forgery
plug :put_secure_browser_headers
end
pipeline :api do
plug :accepts, ["json"]
end
scope "/", RewardappWeb do
pipe_through :browser
#get "/", PageController, :index
#NEW ROUTES
#get "/users", GrantController, :login
get "/admin", GrantController, :admin
get "/main", GrantController, :main
get "/", GrantController, :index
post "/", GrantController, :login
get "/add", GrantController, :add
post "/add/:id", GrantController, :update
get "/admin/delete/:id", GrantController, :delete
end
if Mix.env == :dev do
forward "/mailbox", Bamboo.SentEmailViewerPlug
end
# Other scopes may use custom stacks.
# scope "/api", RewardappWeb do
# pipe_through :api
# end
# Enables LiveDashboard only for development
#
# If you want to use the LiveDashboard in production, you should put
# it behind authentication and allow only admins to access it.
# If your application does not have an admins-only section yet,
# you can use Plug.BasicAuth to set up some basic authentication
# as long as you are also using SSL (which you should anyway).
if Mix.env() in [:dev, :test] do
import Phoenix.LiveDashboard.Router
scope "/" do
pipe_through :browser
live_dashboard "/dashboard", metrics: RewardappWeb.Telemetry
end
end
# Enables the Swoosh mailbox preview in development.
#
# Note that preview only shows emails that were sent by the same
# node running the Phoenix server.
if Mix.env() == :dev do
scope "/dev" do
pipe_through :browser
#forward "/mailbox", Plug.Swoosh.MailboxPreview
end
end
end
Mails are being sent totally fine - I have inspected that with IO.inspect, and right now, they are sent fine. However, I can not attempt to see localhost:4000/mailbox. Where is my mistake? Thank you in advance!!
