## Invoke Lambda transformation via PresignedGET

Following example shows how you can use [`minio-go` PresignedGetObject](https://docs.min.io/community/minio-object-store/developers/go/API.html#presignedgetobject-ctx-context-context-bucketname-objectname-string-expiry-time-duration-reqparams-url-values-url-url-error)
```go
package main

import (
	"context"
	"log"
	"net/url"
	"time"
	"fmt"
