如何使用identityPoolId进行golang sdk的鉴权

当我使用javascript的aws s3客户端的时候，我可以使用如下代码创建s3 client

import { S3 } from "@aws-sdk/client-s3";
import { fromCognitoIdentityPool } from "@aws-sdk/credential-provider-cognito-identity";
import { CognitoIdentityClient } from "@aws-sdk/client-cognito-identity";
const s3Client = new S3({
  region: 'region',
  credentials: fromCognitoIdentityPool({
    client: new CognitoIdentityClient({ region: 'region' }),
    identityPoolId: 'identityPoolId',
  })
});

请问，如果我更换成 golang 的sdk，要如何操作？
