The customOptions prop provides comprehensive access to additional Highcharts options that are not explicitly defined as props.
It’s important to note that certain options may require specific script imports to function properly.

Note: If you are having trouble getting any Highcharts options to work, please match the formatting of our staticOptions. For example, yAxis will need to be wrapped with square brackets.

You may also need to override any of the defaults in order to get that options to work.
