I got it))
All I had to do is add another bar with the transparent background and border on hover
{
type: 'bar' as ChartType,
label: '',
data: data.map(item => item.thirdValue + item.secondValue + item.firstValue),
backgroundColor: `transparent`,
barPercentage: 0.3,
hoverBorderRadius: 8,
borderColor: 'rgb(153, 102, 255)',
hoverBorderWidth: 5,
},
