Chartjs not giving ‘xLabel’ properly on tooltip

I have a line chart where data is displayed as point elements depending on the X axes (time axis) label.

enter image description here

    // Config chart
    const config = {
      type: "line",
      data: {
            labels: ['ene.', 'feb', 'mar.', 'abr.', 'may.', 'jun.', 'jul.', 'ago.', 'sep.', 'oct.', 'nov.', 'dic.'],
            datasets // ex --> [{ x: 'jun.', y: 90 }]
        },
      options: {
            tooltips: {
                callbacks: {
                    title: function(context) {
                             console.log(context); // Returning wrong xLabel 
                           }
                }
            }
      }
    }

The problem is when it shows the tooltip of, for example, June it takes it as index 3 so the title tooltip (xlabel) is shown as “April”.

How could I get the proper label on the tooltip, not depending on the index?
