How to use the selector.allXModules function in selector

// use id as initial moduleName
                var moduleName = module;

                // customize module name
                if (module === 'other') {
                    moduleName = i18n['selector.other'];
                } else {
                    // fetch module name, if module is an moduleId
                    var moduleInfo = CMS.getModule(module);
                    if (moduleInfo) {
                        moduleName = moduleInfo.name;
                    }

                    // add All  Modules selector
                    var allXModulesTitle = JSON.parse(JSON.stringify(i18n['selector.allXModules'])) || ['{moduleName}'];
                    Object.keys(allXModulesTitle).forEach(function (key) {
                        allXModulesTitle[key] = allXModulesTitle[key].replace('{moduleName}', moduleName);
                    });

                    var allXModulesSelector = '.' + module; // TODO: legacy modules added &.moduleId
                    selectors.unshift({title: allXModulesTitle, selector: allXModulesSelector});
                }

                // add to list
                allModules.push([module, moduleName]);

                // save selector by module and selector config by selector
                selectorByModule[module] = [];
                selectorConfigByModule[module] = {};

                var addSelectors = function thisFn(module, moduleSelectors, hierarchy) {
