Export data methods not found on chart reference

Is it possible to call the exporting methods (ie: toCSV()) from the chart reference? I'm capturing the instance using the callback method on the highchartsChart directive, however there is no toCSV() method available. I'm importing the export libraries and can perform the export via the chart hamburger menu, but not from code.

Relevant code is as follows:

```

chartInstance(chart: Highcharts.Chart) {
console.log(chart.toCSV());
}

provideHighcharts({
modules: () => {
return [
import('highcharts/esm/modules/exporting'),
import('highcharts/esm/modules/export-data'),
import('highcharts/esm/modules/map'),
]
}
})
```
Using:

```
"@angular/core": "^20.3.0",
"highcharts": "^12.4.0",
"highcharts-angular": "5.1.0",
```
