Using haxe.macro.TypeTools fails

I'm trying to debug a library which uses haxe.macro.TypeTools::findField. I've created a simple code for that:

package;

using haxe.macro.TypeTools;

class Main
{   
    public function new()
    {   
        var test = findField(Child, "hello");
        trace(test);
    }
}

class Base
{
    private function hello()
    {
    }
}

class Child extends Base
{
    public function new() {}
}

However I'm getting error Unknown identifier : findField. Is this because it can only be used in build macro context?

Thank you!
