Export options - row selector

user3770935

As shown in the example in the link at the bottom, exportOptions which is used to only export and print the selected row(s).
Can we use this when using an excel button? I have tried:

            {
                extend: 'excel',
                text: 'Download Excel',
                exportOptions: {
                    modifier: {
                        selected: true
                    }
                }
            }

Which does not work. The documentation I am trying to apply to excel is below:

            extend: 'print',
            text: 'Print selected',
            exportOptions: {
                modifier: {
                    selected: true
                }
            }
        }

Please ignore me, my code was bad. This is entirely possible:
