Yajra Datatable export all the records - export-to-csv

Question

I am using yajra Datatable in laravel 9. I integrate their buttons like: copy, csv, excel, pdf, print.
When I want to export/print it just exports the records that are only visible to table (10 records).
But I want to export all the paginated records also. How can I do it? Can you give me any Solutions?
My Controller,
public function index(Request $request){
if($request->ajax()){
$data = YajraDataTable::select('id','name','email','phone')->get();
return Datatables::of($data)
->addIndexColumn()
->addColumn('action', function($row){
$btn = 'Edit';
return $btn;
})
->rawColumns(['action'])
->make(true);
}
return view('admin.yajra.index');
}
My Blade file,
<script type="text/javascript">
$(function () {
var table = $('#user_datatable').DataTable({
processing: true,
serverSide: true,
responsive: true,
autoWidth:false,
ajax: "{{ route('yajra.datatable') }}",
columns: [
{ data: 'DT_RowIndex', name: 'DT_RowIndex', orderable: false, searchable: false },
{data: 'name', name: 'name'},
{data: 'email', name: 'email'},
{data: 'phone', name: 'phone'},
{data: 'action', name: 'action', orderable: false, searchable: false},
],
dom: 'lBfrtip',
buttons: [
{ extend: 'copy', exportOptions: { modifier: { page: 'all', search: 'none' } } },
{ extend: 'excel', exportOptions: { modifier: { page: 'all', search: 'none' } } },

],

});
});
