Thanks for contacting Syncfusion support.
We have checked the reported query “To hide the closed button in the column chooser window" and you can achieve this by customize the style of column chooser and set visibility collapsed to the window closed button.
but theres one problem left, this ColumnChooser you provided always shows all columns inside the list and dont interacts like the normal one. Can you provide a sample based on this design but the original behavior of ColumnChooser please.

Sorry for the inconvenience.
We have modified the sample based on the column chooser architecture and you can download the same from the following location.
