How to enable tooltip for line segment in Line Chart with Chart.js

Question

I am able to configure the line chart tooltip when I hover over the datapoint. However, I would also like to show some data if hover is over the line segment between two data points. Code I am using is as follows :

callbacks: {
                  label: function (context) {
                    var value = labels[context.dataIndex];
                    for (var i = 0; i < flares.length; i++) {
                      // console.log(labels[ctx.p0DataIndex], flares[i]);
                      if (
                        value >= flares[i].Starttime &&
                        value <= flares[i].Endtime
                      ) {
                        return "Peak-Score : " + flares[i].PeakScore;
                      }
                    }

                    return "No flares";
                  },
                },
