I'm trying to integrate SIWA with AWS Cognito, but am running into issues on the native iOS app. I'm able to successfully sign in on the AWS hosted UI after configuring with SIWA. On the native iOS app, I'm able to get the auth token and decode the JWT token. However, once I send that token to AWS using func finishedWithAuth this is when it fails to send to AWS and authenticate with my identity pool there. Here's code I have so far following the documentation from SIWA with AWS Cognito (I can't link it here). Here's the error I get from line 28: {"__type":"NotAuthorizedException","message":"Token is not from a supported provider of this identity pool."} 2020-06-23 10:48:29:047 wolf-ios[1879:1393080] GetId failed.
