title: AWS Step function task token sendTaskSuccess cross region
body: <p>I have case where the task token is received as an input from [Account A Region A] to the lambda deployed in [Account B Region B]. When sending the <code>sendTaskSuccess/sendTaskFailure</code>, should the lambda in Account B create <a href="https://sdk.amazonaws.com/java/api/latest/software/amazon/awssdk/services/sfn/SfnClient.html" rel="nofollow noreferrer">sfnClient</a> with Region A for this to work?</p>
  <p>Are the task tokens region specific?</p>
  <p>The problem is we only receive the task token as an input in Account B (no info about the region).</p>
