GitHub request get a repository

Question

How can I make a get request to a repository if my user hasn't generated a personal token and I have just the access token from authentication with oauth2? I have tried some options with postman but I can't fix it. I want to access a private repository

What I'm trying to do:

require "uri"
require "net/http"

url = URI("https://api.github.com/repos/username/repository_name")

https = Net::HTTP.new(url.host, url.port)
https.use_ssl = true

request = Net::HTTP::Get.new(url)
request["Authorization"] = "Bearer ACCESS_TOKEN"
request["Cookie"] = "_octo=GH1.1.1832634711.1663350372; logged_in=no"

response = https.request(request)
puts response.read_body

    json = JSON.parse(response.body, symbolize_names: true)   
    if eval(response.code.to_s) === 200
      redirect_to @group.git_url, allow_other_host: true and return
    else
      flash[:notice] = "You have not the access to this repository, please conctact the admin"
      redirect_to @group and return
    end
    
  end
