bulk-edit-fill class not coming for FileField in Bulk_edit option

[vmathurpaytm]

Model

file_item = models.FileField(blank=False, verbose_name=_('ABC'),)

Admin

bulk_list_display = ['file_item']

Expected behaviour

Want this file field to be copied over selected assets for bulk_edit

Actual behaviour

copy button is missing (class=bulk-edit-fill is not applied) over selected assets for bulk_edit for FileField

Tried Code (fill-fields.js)

`

      // Fill fields in bulk edit and split asset forms

              $('body').css('position', 'relative');

              $('input').attr('autocomplete', 'off');

                        file_field_selector(input_id, $fields)
                    }

                    }
                    $fields.closest('td').addClass('fill-changed');
                    $fields.closest('td').animate({backgroundColor: 'white'});
