How to enable and verify FIPS with aws golang sdk v2

[sandakith]

Hi if we are to use FIPS aws endpoints with v2 golang this is the approach I took but find very hard to verify if it does the correctly use FIPS endpoints, any point would be appreciated
cfg, err := config.LoadDefaultConfig( context.TODO(), config.WithRegion(*regionFlag), config.WithUseFIPSEndpoint(aws.FIPSEndpointStateEnabled), )
Lets say I am using s3 client after
s3client = s3.NewFromConfig(cfg)
How can I verify this client is using FIPS urls not default s3 urls?
