addons/base_import/static/src/jc/import_action.js

In these lines:

$fields.each(function (k,v) {
    var filtered_data = self.generate_fields_completion(result, k);

    var $thing = $();
    var bind = function (d) {};
    if (config.isDebug()) {
        $thing = $(QWeb.render('ImportView.create_record_option')).insertAfter(v).hide();
        bind = function (data) {
            switch (data.type) {
            case 'many2one': case 'many2many':
                $thing.find('input').attr('field', data.id);
                $thing.show();
                break;
            default:
                $thing.find('input').attr('field', '').prop('checked', false);
                $thing.hide();
            }
        }
    }

I want to delete:

"if (config.isDebug()) {"

and

"}"

At the same time, save the code between these lines.

I don't want to change the original code, but I want to create a module that allows you to make these changes. How can I do this?
