How to change DataGrid ColumnOptions filter icon?

[aliastopan]

In customcomparer example, TemplateColumn could have ColumnOptions. This useful for adding column based filtering. But is it possible to change the default filter icon?

You can change that icon by using the HeaderCellItemTemplate but when using that, it is left up to that template to render any relevant
"show options" UI and invoke the grid's FluentDataGrid<TGridItem>.ShowColumnOptionsAsync(ColumnBase<{TGridItem>> .

The code in RenderDefaultHeaderContent in ColumnBase.razor can be used as a guideline.
