Draggable bar graph using Chart.js

Hi all, I posted this question before but it wasn't posted in a very read-friendly way, so here it goes again. I am trying to make a bar graph where you can drag the bars with the mouse. I am using Chart.js with its dragData pluggin, and I am using a source code of a demo provided in (https://www.npmjs.com/package/chartjs-plugin-dragdata, see Bar-Simple demo). I can see the graph perfectly, and the mouse becomes a hand when you put it in one of the bars (as it should be). However, it is weird, because I cannot move the bars. I think that the problem may be that I am not adapting the demo code to Qualtrics properly... But I don't know what else to try, so suggestions are appreciated. Thank you!
Here are the steps that I follow:

1. Look and feel--> Hearder(html) :
```
<script src = "https://cdn.jsdelivr.net/npm/chart.js@2.9.3/dist/Chart.min.js">
<script src="https://cdn.jsdelivr.net/npm/chartjs-plugin-dragdata@latest/dist/chartjs-plugin-dragdata.min.js"></script>

```
2. In the question where the graph goes --> html

```
<canvas height="400" id="myChart" width="400"> </canvas>

```
3. In the question's JS:

```
Qualtrics.SurveyEngine.addOnReady(function()
{
var ctx = document.getElementById("myChart").getContext('2d');
var myChart = new Chart(ctx, {
type: 'bar',
data: {
labels: ["Africa", "Asia", "Europe", "Latin America", "North America"],
datasets: [
{
label: "Population (millions)",
backgroundColor: ["#3e95cd", "#8e5ea2","#3cba9f","#e8c3b9","#c45850"],
data: [2478,5267,734,784,433]
}
]
},
options: {
responsive: false,
dragData: true,
dragX: false,
dragDataRound: 1,
dragOptions: {
showTooltip: true
},
onDragStart: function(e, element) {
//console.log(e)
},
onDrag: function(e, datasetIndex, index, value) {
e.target.style.cursor = 'grabbing'
//console.log(datasetIndex, index, value)
},
onDragEnd: function(e, datasetIndex, index, value) {
e.target.style.cursor = 'default'
//console.log(datasetIndex, index, value)
},
hover: {
onHover: function(e) {
var point = this.getElementAtEvent(e)
if (point.length) e.target.style.cursor = 'grab'
else e.target.style.cursor = 'default'
}
},
scales: {
yAxes: [{
ticks: {
max: 6000,
min: 0
}
}]
}
}
});
});

```
