How can I use lookup_windows.go in a project : I'm trying to use the following package in my project:

    https://github.com/golang/go/blob/master/src/os/user/lookup_windows.go

But I cannot access the functions in lookup_windows.go, because the functions are not capitalized, right?

How can I use this package in my project, e.g. the `listGoups` function?

    package main
    
    import (
    	"fmt"
    	"log"
    	"os/user"
    )
    
    func main() {
    	s := "some sid..."
    
    	result, err := user.LookupGroupId(s) // Can access 'https://github.com/golang/go/blob/master/src/os/user/lookup.go'
    	//result, err = user.listGroups(s) // Can't access 'https://github.com/golang/go/blob/master/src/os/user/lookup_windows.go' 
    	if err != nil {
    		log.Fatal(err)
    	}
    
    	fmt.Println(result)
    }
