How do you customize the TimeSeries chart xTrace infoBox?

Hi forum,

On Timeseries Chart mouse hover,

At least, I would like to ONLY show timestamp on infoBox .

At most, I would like to display custom message, depending on the x-time.

Any way to edit infoBox of timeSeries Chart?

I can't see any reference to 'infoBox' in the https://www.amcharts.com/ documentation. Odd!
