How to access custom property in dataset object in Bar Chart in React ChartJS 2?

I would like to know the "userId" custom property when I click on the element.

If I add a custom property to the dataset object, the custom property added doesn't show in the element retrieved in getElementAtEvent.

Since you barely gave any specifications on where you tried accesing your custom property I went with that it was in the dataset itself, if this is the case you can acces it like this:

onClick: (evt, elements, chart) => {
    alert(chart.data.datasets[chart.getElementsAtEventForMode(evt, 'nearest', { intersect: true }, true)[0].datasetIndex].customProperty)
  }
