title: Cognito group id as S3 folder-path
body: <p>I want to access a spesific folder in S3 where the folder is the cognito group id.</p>
  <p>My api is gated behind cognito so I get the group id from my mapping template</p>
  <pre><code>&quot;context&quot; : {&quot;groups&quot; : &quot;$context.authorizer.claims['cognito:groups']&quot; }
  </code></pre>
  <p>I tryed to use context.groups as a folder name in Path override with no success.</p>
  <p><img src="https://i.gyazo.com/ffa9907f55eceb04e03ad1e0ab19ead3.png" alt="text" /></p>
  <p>Any ideas on how to solve this?</p>
