Presigned URL request java backend

My S3 presigned URL request tries to point to AWS S3 and not localstack even when I use “test” as my aws credentials. Here is my presign request method: (Scrollable)

protected URL generatePresignedURL(String objectKey) {

        S3Presigner presigner = S3Presigner.create();

        GetObjectRequest objectRequest = buildGetRequest(objectKey);
        
        GetObjectPresignRequest presignedRequest = buildPresignedGetRequest(objectRequest);
        
        PresignedGetObjectRequest presignedGetObjectRequest =
                presigner.presignGetObject(presignedRequest);

        
        
        System.out.println("Presigned URL: " + presignedGetObjectRequest.url());
        return presignedGetObjectRequest.url();
    }


    protected GetObjectRequest buildGetRequest(String objectKey) {
        return GetObjectRequest.builder()
                .bucket(bucketName)
                .key(objectKey)
                .build();
    }

    protected GetObjectPresignRequest buildPresignedGetRequest(GetObjectRequest objectRequest) {

        // Create a GetObjectPresignRequest to specify the signature duration ( 5 minute )
        return GetObjectPresignRequest.builder()
                .signatureDuration(Duration.ofMinutes(5))
                .getObjectRequest(objectRequest)
                .build();
    }

Do I need extra configuration on my presign request to explicitly point to my local instance of S3?
My upload file method works perfectly fine on my LocalStack S3 instance.

Thank you.
