Does the AWS SDK for JavaScript V3 handle refresh of expired temporary credentials?

I am developing an application using Amazon Cognito User Pools and Identity Pools. My application uses: * the Cognito Hosted UI and authorization code grant to get an authorization code * a POST request to a standard `oauth2/token` endpoint to exchange the authorization code for an `id_token`, `access_token`, and `refresh_token` * the AWS SDK for JavaScript V3 `fromCognitoIdentityPool` method to exchange an `id_token` for temporary AWS credentials (which are used to allow users to access various AWS services) My question relates to the expiration and refresh of these temporary AWS credentials. The IAM user guide says [here](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp_use-resources.html): > You must make sure that you get a new set of credentials before the old ones expire. In some SDKs, you can use a provider that manages the process of refreshing credentials for you; check the documentation for the SDK you're using. I am using the AWS SDK for JavaScript V3. I have searched through these resources without finding any reference to whether or not the SDK handles refreshing of temporary credentials: 1. [The API Reference](https://docs.aws.amazon.com/AWSJavaScriptSDK/v3/latest/index.html) 2. [The Developer Guide](https://docs.aws.amazon.com/sdk-for-javascript/v3/developer-guide/welcome.html) 3. [Various code files from the repository](https://github.com/aws/aws-sdk-js-v3) I did find one tangential, ambiguous reference to credential expiration and refreshing on the page ["Using Amazon Cognito Identity to authenticate users"](https://docs.aws.amazon.com/sdk-for-javascript/v3/developer-guide/loading-browser-credentials-cognito.html) in the section named ***Switch to Authenticated User***. I think adding a section to this page about the details of temporary credentials refresh would be extremely helpful to developers. **Does the AWS SDK for JavaScript V3 handle refresh of expired temporary credentials? Where is this described in the documentation for the SDK?** If yes: * Does the SDK handle the exchange of a `refresh_token` for an `id_token` and then exchange of an `id_token` for expired temporary credentials? * Or does the SDK require developers to write application code that exchanges a `refresh_token` for an `id_token`? (Meaning the SDK would just handle exchanging an `id_token` for expired temporary credentials)
