The possibility of adding custom icons to add files and add folders

[jzarei1996]

Hi everyone.
How can I put custom icon to add file and folder?
It seems that such a possibility does not exist at the moment, so please add it.
Thanks.

export interface IconComponents {
CancelIcon?: Icon;
CaretRightIcon?: Icon;
CaretDownIcon?: Icon;
DeleteIcon?: Icon;
EditIcon?: Icon;
FileIcon?: Icon;
FolderIcon?: Icon;
FolderOpenIcon?: Icon;
OKIcon?: Icon;
}
