title: How to use AWS Amplify GraphQL APIs if I have access token of a logged in user?
body: <p>I am completely new to Amplify library. I have logged in my user using Cognito User Pool. I have the required access token (jwt token). How should I go about using AWS Amplify APIs for GraphQL using this access token?</p>
  <pre><code>Amplify.API.query
  Amplify.API.mutate
  </code></pre>
  <p>Reading the documentation, it seems to me I have to login user using Amplify Auth only to use these APIs. In other words, how do I let Amplify know that I have access token of an authenticated user and allow me to use GrapQL APIs? Or authentication via Amplify Auth is the only way?</p>
