I have successfully overwrite core file: MagentoSitemapModelResourceModelCatalogProduct

but getting error in public function getCollection($storeId) for this: $this->scopeConfig->isSetFlag and $this->getConnection() method not found.

When try to overwrite whole file getting this error:
Incompatible argument type: Required type: MagentoSitemapHelperData. Actual type: string;
