Tools API for onDrop, onDragover, etc?

Editor.js does not have API methods for drag and drop operations. I'm trying to do something like this:

```
onDrop(event){
alert("onDrop executed");
}

onDragover(event){
console.log("onDragover executed");
}

```

Would modifications need to be done to the source code or is there a way to handle this without touching the source code? Thank you.
