You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: assignee_mailer.rb
    path of file: ./repos/chaskiq/app/mailers
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

class AssigneeMailer < ApplicationMailer
  def notify(conversation)
    @conversation = conversation
    @assignee = conversation.assignee
    @app          = conversation
    
  def notify(conversation)
    @conversation = conversation
    @assignee = conversation.assignee
    @app          = conversation.app
    from_email    = "notifications@#{@app.outgoing_email_domain}"

    subject = "you has been assigned to a conversation on chaskiq"

    mail(from: "Chaskiq notifications <#{from_email}>",
         to: conversation.assignee.email,
         subject: subject) do |format|
      format.html { render "assignee_mailer/notify" }
      # format.text # assuming you want a text fallback as well
    end
  end
