title: How to send oauth2 access_token in cookies ? (kong oauth2 plugin)
body: <p>I am using Kong oauth2 plugin to handle authentication for my dash plotly app. Dash plotly does not allow the user to set a custom header for the requests and so it very difficult to add an authentication header to my requests.</p>
  
  <p>These headers work perfectly for normal web pages
  <code>"Authorization": "Bearer snakjdnjsbcksnbnddnndnsms"</code> or
  <code>"authorization": "snakjdnjsbcksnbnddnndnsms"</code></p>
  
  <p>However, due to the limitation of Dash Plotly not allowing to set the headers I want to try to send the authorization token in a cookie.
  I tried sending a cookie with the "authorization" key and corresponding value via my flask app, however I still get an unauthorized response.</p>
  
  <p>Is this method even possible ? I saw that it works in loopback.token of nodejs using signed cookies. If so how can I achieve this ? Appreciate any help in this regards.</p>
