Distinguishing between left and right click event of column chart series

I am trying to accomplish right and left click(clicking on the series) functionality on the series of a column chart. The left click is going to fire an event whereas the right click is going to show a context menu. The left click is working fine but as soon as I right click on the series, left click is fired first then the context menu appears. How can I distinguish between those two clicks? This is the code I have written inside the series config for left click:

Code:

 series:[{
    .
    .
    .
    listeners: {
                  itemmousedown: function (_chart, e) {//function being called on both the clicks.
                  //need to distinguish between left and right click
                  var _item = _chart.storeItem.data.EmployeeName;
                  //further functionality
                  }
                }
    
    }]
