How to give time labels consistently in polar highcharts?

Hi i am working on highcharts i am having a polar chart and i wanna display on y-axis time consistently. This is the one which i tried so far:

Here my labels are [06:00,08:00,.....20:00]

But how to make consistency like upto 24:00, 02:00, 04:00 so that i will be able to hover some of the values which i cant see properly now.

And my expected outcome should be like this: [02:00, 04:00, ......24:00]

Highcharts.chart('container', {
      chart: {
        polar: true,
        type: 'scatter',
      },
      
        xAxis: {
          type: 'datetime',
          showLastLabel: true, 
        },
        time: {
        useUTC: false
      },

  yAxis: {
    min: 0
  },
