How to run AWS SDK version 2 with credentials from variables?

Question

My question is the same as this other question: How to run AWS SDK with credentials from variables? but I am using SDK version 2 which no longer uses Session (if I understand correctly).

So, I am creating a new client, and I have the credentials as variables. I need to use the IAM service. Here is the function:

func getIAMClient(ctx context.Context) (*iam.Client, error) {
    cfg, err := config.LoadDefaultConfig(ctx, config.WithRegion("no-region"))
    if err != nil {
        return nil, errors.Wrap(err)
    }

    cfg.HTTPClient, err = getHTTPClient(ctx)
    if err != nil {
        return nil, err
    }

    return iam.NewFromConfig(cfg), nil
}

Different users will use the app at the same time, so I can't just use ENV files, but I haven't been able to find a documentation page explaining how to pass these credentials to my Client. Any support will be appreciated!

This can be achieved with the StaticCredentialsProvider as described in section "Static Credentials" of the AWS SDK for Go V2 documentation:

cfg, err := config.LoadDefaultConfig(ctx, config.WithCredentialsProvider(credentials.NewStaticCredentialsProvider("AKID", "SECRET_KEY", "TOKEN")))
