Show axis ticks only for the shown labels

[clmz]

I'm still struggling with migrating our project from v4 to v5 and it's such a mess since so many things are not documented or just don't work as expected, that's so frustating ...

Simple example:
I only want ticks for the labels that are shown on the x axis, but this is what I got:

I v4 the chart itself calculated the number and position of ticks regarding to the number of the formatted labels automatically. Now this doesnÄt work anymore and I have (after hours of trying every constellation of scale ticks, label settings and so) no clue hwo to solve this.

The config of my axis looks more or less like this:
chart.encode('x', 'timestamp').scale('x', {nice:true}).axis(
'x',
{
tickStroke: 'white,
tickLineWidth: 2,

            labelFill: white,
            labelFontSize: 12,
            labelFormatter: (t: string | number | Date | null | undefined) => {
              return hasValidTimeStamps
                ? getTimeString({ timestamp: t, format: chartOptions.dateFormat ?? 'dateAndTime' })
                : t;
            },
            labelAutoHide: true,

            title: false,
          }
    );``
    
   My data contains data series of every 60 minutes, timestamps are like this: "2024-01-04T14:00:00.000Z",  

"2024-01-04T15:00:00.000Z" and so on:

How do I manage to show only one tick per label at the correct position?
