h5p-drag-text doesn't implement attach()!
Was hoping to use h5p-drag-text as the basis for a new content type so am working my way through its code on GitHub but cannot find the .attach() method I was expecting to see, having read the developers guide...the closest I can find is:
DragText.prototype.addTaskTo = function ($container) {
Is this a deprecated method which is still supported or am I looking at the wrong code?
